GPS Navigation Help

Thanx guys! So far I have been looking at the Garmin models. They seem to be well-liked and reliable. I was looking at the garmin c330 and c340 since they are more around my price range.

I went to Best Buy and Circuit City today to get a feel of how these models look and compare to others.

I don't travel all over the country. I mainly travel all over the boroughs in NY and sometimes I have to take different routes and it's a pain to have to go on Yahoo Maps/Mapquest to figure out my route for that particular day.

Now I'm just trying to figure out if it's better to buy a GPS system that has preloaded maps or one where I have to download maps onto the system.

I'm going to check out the links you guys have posted so far....Thanks again for all your help!
