I had a old Garmin 200 that I loved oh so much, but when a friend decided to move 3000 miles I gave it to him. He played with it for about a week before he left and it got him from his old house to his new one with no issues. He used it to find places to eat and hotels along the way.
He loves it and still uses it...as for me I was forced to buy a more expensive model with a larger screen...Oh woe is me!
Between a TomTom and a Nuvi [garmin] I give the nod to the Nuvi, easier to use, more pleasent to look at, and its very no nonsense. I haven't used anything beyond a Garmin and a TomTom but I've bought two Garmin GPSs and I'm very satisfied with both.
On a side note, if you can find a Garmin Nuvi with Voice reconition its so worth it! All I have to do while driving is push a button that I mounted on my steeringwheel and say a word and say the address of where I want to go and it pulls up directions for me and start navigating.
Just like a MP3 player a GPS is something you wonder how in the heck you lived without once you start using.
