Why not just visit the re-seller "service announcements" and buy it comparable price with them? plus they are in the states as well..
Yeah, I've looked at that and I've made 2 purchased from Ninjatech in the past. Unfortunately (or fortunately depending on your point of view), the resellers that do have S1's in stock are charging a premium over the regular price. That's why I specified used gear. I'm not personally interested in paying more for these, at this time.
I hope you do not take offense by this, but you picked a bad time to buy if you do not wish to pay more. The "new gen" Miners are backordered everywhere and it seems that even official bitmain distributors do not know if the s1 is coming back or not.
My gut is telling me that bitmain was either selling of the remaining s1's cheap to make room for the s2's in prodution or they just realized the cheap s1's were killing the market for the s2's. Either way I think the days of dirt cheap s1's are done, but I guess only time will tell.
More on topic, I have a few s1's that are used and currently mining and some new ones scheduled to arrive on Monday, you are welcome to make offer on some in either lot but like pretty much everyone I will not be letting them go cheap.
