Hey. Ive done some research, but all I find around are GPS worth not less than 300$... Ive got a limited budget for a trip. But I need a good GPS, that will work for another 2 years... Something small but powerful.
And not too expensive. Anyone has any ideas, or did already purchase something similar?

Thanks

Garmin 305 is good.

Ebay has the Garmin Legend (non color) less than $100.00 dollars. Add the Software and your set for under $200.00

How soon are you looking to pick one up? I have a 305 that I have used since they first came out in early spring of '06 that I will be selling on eBay as soon as my 705 arrives. I dont have an exact price but if you can wait about a month or so I we could talk. It will have a brand new speed/cadence sensor and HR strap.

PM me if you are interested.

Do you want a moving map display? Do you plan to preload the route and use the GPS to guide all your turns? How large an area will you be cycling?

I used to use a Magellan Sportrak Pro. I used the accompanying software to preload the route so it would guide me on every turn. It took several trips before I perfected the details to where it was very useful beyind just watching my progress on a moving map display. I have since upgraded to Garmin GPSMap 60Cx and the convenience difference is HUGE. I have all the software and cables and mounting brackets for my old device, and was planning to put the whole package up on ebay for maybe $100. But I would stress that my new Garmin ($250 unit plus $100 map software plus $25 mounting hardware plus $40 microSD card == $415) is way worth the added cost for convenience and usability. I would never go back to the old device, nor have I gone to the effort of mounting the old one on another family member's bike when we go on long trips. It would definitely be useful simply as a moving map display, but for preplanned routes, it's not worth the effort (to me) for older technology.

I have done a bit of research into GPS units. To me, the only GPS worth spending any money on are WAAS enabled (this provides significantly improved accuracy, from 50 meters down to 10 meters or less), have expandable memories through flash card readers, and allow for the addition of better maps. Most experience GPS users will tell you the standard basemaps are terrible.

The best on the market have the faster chipsets (such as the SIRF in the Garmin Etrex Vista HCx or whatever is used inthe Delorme Earthmate PN-20).

If I was to buy a new GPS today, I'd get a Delorme Earthmate PN-20 because it meets the requirements above, as well as it comes with Delorme's excellent Topo USA 7.0, detailed topo maps of all 50 states. For $300 this, in my opinion, is the best value in GPS.

The PN-20 looks nice from the review (http://www.gpsreview.net/delorme-earthmate-gps-pn-20/) I read, but this review (http://gpstracklog.typepad.com/gps_tracklog/2007/01/delorme_earthma.html) points out that the vector maps ger kind of pricey. Do you need to have the vector maps to use it? How is the battery life? Has anyone used this succesfully with a Mac?

Please note, I do not have a current GPS. I am still using an old Garmin GPS 12, but have done a bit of research because my kids and I enjoy geocaching, so we've been considering a new one.

I am a devoted Mac user myself. My understanding is that none of the major GPS makers are truly Mac compatible. Go to the forums at Geocaching.com and you can read all about it. What most people do is introduce a 3rd party software that seems to fill the gap, or they have Windows Bootcamp on Mac OS X 10.5.

The PN-20 comes with the Delorme USA Topo atlas as a basemap. This means you don't need to purchase any additional maps to use it. The Garmin units require you to purchase Garmin Topo (1:100,000 scale) to have any kind of detail, and from the reading I've done, Garmin Topo isn't as good as the Delorme Topo (I believe Delorme Topo maps are 1:50,000 but allow you to zoom in to 1:24,000). The vector maps you ask about are significantly more detailed than either the Garmin or Delorme Topo. They are not required to use the PN-20. However, this is what makes the PN-20 unique: you can add significantly better maps to it, if you choose to pay for them. This isn't even an option with any other major manufacturer.

I use a Palm TIX and Cetus GPS Software. Maps from google and yahoo can be saved and renamed to use on a SD card for map display. You may also scan paper maps and add notations as well. Something not possible with GPS only units. I even have the ability to use a Wi-Fi hot spot to access the internet and e-mail. I use my dynamo with a custom circuit to operate the Palm and GPS receiver as I pedal along so I never need to worry about stopping to find a outlet to recharge them.

I just got new Navigon 2100 GPS (http://www.dealstudio.com/viewtopic.php?t=35597&ru=290) at a deal price of $150 for my brother, it is slim, stylish, easy to use, and has features no other GPS navigator has. It looks very slick with a nice display and shell. It also has a great review (http://www.terrywhite.com/techblog/?p=377).

That looks like a great GPS for in a car. It doesn't appear to be designed for outdoor use. Car GPS units are often cheaper than handhelds because: 1) they don't need to be as rugged 2) they don't need to be waterproof. I'm sure on a bike, you'd want both of these characteristics.

Good luck!
