I purchased my refurb TomTom 130 from Amazon on July 1st for $70 - $20MIR, and it arrived like-new with all the accessories. I was even lucky enough to qualify for free map updates (best of all, the new maps just came in on June). If you plan to do a lot of crowded city driving, then I suggest the TTS version. Otherwise, the regular version should be good enough.
Also, I have no clue why people give the device one egg just because they couldn't update their map. TomTom explicitly claims, and has been claiming, that they do not guarantee map updates for refurb units.
