I have a friend who uses a Tomtom One gps and sometimes it takes a while for it to find signal...but he also doesnt mount it on the dashboard, he holds it in his hand =/

But I know two other people with a Garmin gps, mounted on dashboard and it works great. Plus I've heard Garmin is the best.

So my question is, should I buy a Tomtom GPS for $100? It's on sale, usually $180. Or should I buy a Garmin (and maybe wait til it goes on sale).

Why one vs. the other? I want the most reliable one.

Thanks.
