Hot! Buy.com - TomTom GO 510 Portable GPS System (Refurbished) for $199.99 Shipped Free!
 

I paid a little more for my TomTom GO 500, which is still very good, but a tad bulky and a smaller screen. The GO 510 has a much thinner footprint, and a larger 4" widescreen. All the maps come included with the 1GB SD memory card. This is a GREAT buy if you need an inexpensive portable GPS system that you can move from car to you. It's got a built-in rechargeable battery, so you can even take it with you when you walk around! TOMTOM GO 510 PORTABLE GPS SYSTEM REFURBED SALE
