I am planning to buy my first GPS. I have been comparison shopping for a while and found a few sites that seem to be doing a good job with pricing and customer service. I am still confused and undecided as to what to buy with all the various options. The folks at getfeetwet.com (quite helpful) have suggested the Garmin Edge Any thoughts on this unit?? Garmin gives 1 yr warranty looks like getfeetwet adds a 2nd yr to that. I was assured that they are as good as new. Has anybody purchased a Garmin Edge before?
