Hi... I want to buy my husband a garmin for xmas but there are so many different models that i am unsure which one to go with. I am currently looking at the 305 on amazon but it looks kinda bulky... any suggestions? Do you like it? Is it worth it? He is an avid runner... currently training for the Disney Full Marathon in a few weeks. I know he would love something like this but I want to make sure I get the right one! Thanks 
Jessi
