I have a timex ironman. I really like it, it has an easy to push split button in the middle, and  it is not too expensive (34.99). Also the strap is really comfortable, it is light, and not big.

if you want basic i love my Nike Presto watch...

i often alternate running and walking and it's easy to stop and start the timer as i run...

Amazon has a bunch of colors...nordstrom has them in store if you want to try it on (don't see it on their website though)

I second Campmor.

My wife bought me the Timex Ironman Triathlon with the 100 Lap memory and Speed + Distance System. I have found the GPS to be accurate and easy to use. Obvouisly you cant use the GPS swimming and you don't want to hit any of the watch buttons when it's submerged but I have swam with it many times and no problem. I really like the fact that I can set a split while doing a brick as I move from the bike into a run. Having one unit through the workout is nice coming from a Tri perspective. It was $70.
