Then I guess my question is.  Will the difficultly go up much from now to when the next batch is available?  The reason is I'm getting a loan to buy this and my buddy is asking me to pay him back 2x the price in 6 months.  So should I buy one from a reseller now, or will the difficulty be fine and mean that I can buy it from Bitman themselves when the next batch comes out?  Which will be around September?
