I did a search, but couldn't find much relevant recent information, so here is my own, personal GPS thread. (:

I currently have a regular old computer with wired cadence sensor and have Strava running on my phone in one of my pockets and am thinking about upgrading my setup.

• The major reason for upgrading would be for live heart rate tracking so that I can train better/understand how I ride better.
• Cadence is still important. Though I can almost tell now how fast I'm spinning, I still want that data to be presented to me live.
• It would also be very nice to not have to tax my phone's battery, so going with a GPS computer would be ideal, but perhaps not 100% required.
• I would like the GPS data to be uploadable to Strava, although this is distant in terms of priority. If I had to start using another app/website for logging rides, I could deal.
• Of note, I use an Apple computer, so any software that the new bike computer has to run through would need to have compatible software. I'd rather not install windows just for this purpose.

I looked through Garmin's line, and it looks like I'll need the 500 bundle at the minimum to satisfy all my requirements. Is that your understanding as well, from what I've presented? What would be the major reason to step up to the 510?

I haven't looked at any other company's lines of GPS units. What would be comparable from someone else? Would I save significant money by going with another company? It seems Garmin is far and away the most preferred, at least in the Road forum.

Lastly, are there any non-GPS computers that would give me heart rate and cadence that you would recommend that would save me enough money to convince me to keep using my iPhone for logging the rides via Strava?

I realize that's a lot of questions. Sorry about that. (: Thanks for all the help!
