I will say this. I just got the wife a Tomtom from target for $50. It was on clearance. That's better then any BF deal that is going to happen this year.
As for choices, I have 2 gps units myself. I got a Garmin and a Staples cheapo that I got for $35 after rebates and so on. The software I like the best is Navigon. To each their own.
