Geko 201 doesn't come with the cable. That's another 25-30 bucks. By the time you add the cost of the cable, the Legend is about the same price.

If you don't want mapping, the GPS 60 is way overpriced by what you need.

If you want a real barometic altimeter, then you'll need either the Geko 301, Etrex Vista or the Garmin Venture if you can find it. I find the GPS barometer to be fine with me which any unit will have.

I would recommend the Etrex Legend (around 150 bucks) and it comes with the data cable. It's a very popular unit. Although you don't want mapping, these cheap unit just happens to come with a base map. It also has something the Geko and Etrex Yellow doesn't have and that is a data screen that can track up to 8 fields at one time. I find that to be the most feature myself. At the bottom is a screen shot from the Legend Color but it is identical to the Legend BW. You can change it to bigger numbers if you want.

Magellan makes the Explorist series which also will have some of the features you want. The 210 is probably the unit that is closest to your needs.
