the amount you guys get back will probably not be the price difference from what you paid now and $950. That would mean you guys got an even better deal since you got it cheaper and get to mine with it for a week or two. That extra week or two is worth a fair amount so I would assume the 2 week ago purchases will get less than the one week ago purchases (maybe 150-200 per week per machine?). I just bought one when the price dropped to $950 now so I am content.
150-200 per machine per week??? Not in those market conditions, its more like 50-60 usd per week.
