does 1721 seems like a good deal to get a potentially buckled, crippled miner with awful support & 'more virtual coupons' if your rig is a lemon?
There's always the risk of damage in transit regardless of the vendor, but my last S2 made it to FL in perfect shape in 3 days. Bitmain has always responded to my emails so I can't complain. What rig would you suggest instead?
