i'm having a similar dilemma. want something that does running and biking. ha a good battery life, and good online support. and something i can wear as a watch in the meantime.
global trainer is cheaper these days but then it's 2 years old so presumably not long off getting replaced. the gps bugs appear to have been fixed. hear good things about the run trainer but not great for cycling. the garmin 610 gets a good write up but is still pretty expensive, and the motoactv gets mixed reports but has come down alot in price and has battery life issues (and not waterproof). it's probably also due an upgrade.
what to do - just need to make a bleedin' decision don't i?
