I wanted a set that I could use in the gym and while running that was budget-friendly. In the end, I went with the MotoROKR S305s because I could get them for half the price of either of the other two, shipping included. I haven't yet received them, but this was a decision I bounced back and fourth with since buying my Droid in early March.
MotoROKR S305 at Buy.com for $33.95, free shipping.
The S305's are awsome! One thing though, you said that you want them to use while working out. One of the only negative reviews I saw about the 305's before I bought them was that sweat can soak into the earpads and damage the internal componants. Make sure to take extra caution with them if you are sweating a lot.
