I "bought" a NAS from osoo, said in stock, next day delivery - got confirmation email of order but then no dispatch email. PHoned - went to answerphone, left message, no one phoned back.
Sent email, got response around 48 hours later - said not in stock and i could get a refund - replied asking for refund.
3 days later no sign of refund (onto credit card) emailed again - got a refund eventually.
He may be sitting on a pile of Pre2s in which case i suspect its fine to order one - from looking at online reviews (hindsight a wonderful thing) i suspect he does carry some stock. However from the look of things, and my experience, he takes lots of orders for items he doesn't have in stock, presumably then trying to get then and sell on before the customer get fed up.
My advice is avoid.
