I wanna chime in because I bought got one of these 3 weeks ago from superufo. It came a lot faster than I thought it would, and it works fine. There might be variances in shipping time, but from what I've heard in /r/vita, it's come fast for anyone else who's ordered from there and I haven't...
So I've just gotten my Vita, and putting in the game while it's on shuts off the Vita. With said game in, I cannot turn the Vita on until I take it out. What's wrong? A search hasn't yielded any results that really help and I want to play my Vita :X
I can also confirm the Best Buy clearance, went to check BB out today and sure enough I saw one there. Hopefully you can find one there if you haven't already.
