the question is, do you really need some kind of GPS? I'm thinking to changing my computer too since i dropped it and the screen partially broke. I'm interested on Cateye smart computer since they can sync with your phone and uses a speed sensor that's more accurate than GPS data for speed calculation in my opinion.

in other words,
what feature do you need form a cyclocomp?
do you really need that feature? (GPS? Cadence?)
do you like the models? (this is important)
where do you want to put it? (some can be putted on handlebar, some on Stem, and some are off handlebar)
