BuyDig via eBay offers the refurbished Garmin Nuvi 2757LM 7" GPS with Lifetime Maps, model no. 010-01061-00, for $99.99 with free shipping. That's $10 under our mention from four days ago and the lowest total price we've seen. (It's a current low for a refurb by $50.) It features a 7" color touchscreen, text-to-speech turn by turn guidance, lifetime map updates, and emergency service locator.
Note: A 1-year warranty applies, but it's unclear who backs it.
