Mine is awesome. I had my pre-ordered at eb and it was the last one left. I had to wait 2 days to pick it up and the clerk told me people were gawking over it and offering him 150 bucks for the stick.
Mine works flawlessly and have had no sticking issues as of yet. (15 hours played)
It works beautifully with windows vista 32 bit and it installed the drivers automatically. I have a blast playing mame with it.
So far I give mine a 10/10
