We just got a Magellan 3250 from HSN this past spring for just under $200, which I thought was a pretty good deal.
It comes with 6 million points of interest and AAA ratings and guides. Since we are AAA members we were able to get a two year warranty over the standard warranty. AAA & Magellan have teamed up, so if AAA is important to you it may be a brand you want to look at.
It also has a bluetooth connection, so we can do hands free calling from the car. It's not as good as our hands free bluetooth in the radio of our other car, but it works in a pinch. It also has the text to speech which tells the street names.
I was concerned about the 3.5", since I too thought a 4.5" would be better, but it has worked out OK so far, though the onscreen buttons are a bit small.
Someone who is a GPS expert may explain the difference say between a Garmin and Magellan over a Tom Tom. My understanding is that some people believe the mapping technology in the Garmin and Magellan is better than the Tom Tom. I don't know, but I know some people comment on this on other forums or guides.
Good luck
