I recently bought a refurb 2730 from bobwv203 for $189. He has more on sale now for $185. Full package with all the cables, wires, adaptors, antennas, manuals, City Navigator North America 2008 DVD with unlock code, everything.
It was shipped immediately, packaged perfectly, looks brand new, and has everything he listed. And it works perfectly.
A real fine upgrade from my 2610.
No connection with the guy, just a happy customer.
