The cheapest GPS V I see on pricewatch is $459.

My own GPS receiver is a Magellan something which was $260 at Fry's. Has a display.

Laura, if you just need coordinates and compass directions, you can almost certainly find something for on the order of $99, maybe a bit less.

I don't remember, do you have a Palm device? I recently got my wife something for hers for $40.
