My gpus are mining ltc and when that becomes non profitable I sell them. You cannot resell ASIC if the diff is to high to make money which is a matter of time. So many people are going to get burnt with the pre orders, always a good sign to run and sell into the hype.
those gpu's eat the electric though which isnt cheap in the UK. When ASICs hit bitcoin all those GPU miners will jump to litecoin too so probably not worth buying into GPU mining at the moment.
I think you mean "mhash", not "khash". The payback on the 2.1BTC 330Mhash USB sticks is about a year at current difficulty. Obviously diff is going to rise A LOT in the next 6months, so payback will likely be several years. But ASICMiner shares at 2.5BTC/share look fairly priced to me. If we assume that ASICMiner keeps 20% of the network through a combo of direct mining and hardware sales, it'll earn 2.5BTC/share in just shy of 4yrs. So the USB sticks *might* actually be better. Really tough to know; the market has actually priced these shares pretty well, and ASICMiner has priced their hardware to match.
