If you would like to check out streets and trips with a gps receiver for the laptop.
There is an ebay store called "trading circuit". They are apparently affiliated with "circuit city" retail store.
Some items are customer returns scratch and dent sales and stuff that is overstock or has parts missing. The prices are at a major discount.
There is Microsoft Streets and Trips 2006 with GPS.
They always seem to have this item on their site. Beware of the parts that are missing or condition. But you can get the software and the receiver for (what I've seen) $30 ~ $60 bucks depending on condition. Then there's the approx $10 bucks shipping. I still think its a bargan just be sure of what you are bidding on if you decide its for you.

This item requires a laptop and is not a standalone GPS reciever.
I haven't bought one nor do I own the unit. Just though you might want to know about this site.
I use a Garmin Streetpilot and can interface it to the laptop.
