i don't know, i'm happy with my purchase, consulted on IRC before ordering, was told it was in-stock and would ship shortly. placed the order for the x2.3b-pro on 12/31, shipped on friday (due to New-Years day holiday) no problem.
recieved it just now, 1/7, roughly one week after i ordered. came boxed in a USPS-PM envelope, looks good, haven't had it installed but it's exactly what's expected.
price, terrific, paid $50 including shipping, can't beat that.
so, in my experience, i would definitly order again
