coupon 300usd? lol, 3200-300= 2900USD
Antminer S2 2200usd - 400usd = 1800usd
Antminer S2 1Th/s x 3 = 3Th/s (3000W) - 5400USD (every day will cut the price of 30-60usd) and shipp FAST 3days.
SP10 1,4Th/s x 2 = 2,8Th/s (2500W) - 5800USD shipp 3-5days?
Antminer S2 - High possibility arrives broken (2/2 arrived broken here, from different batches), haven't been able to keep stable above 1th/s
SP10 - Set up in less than 5 minutes, lower power consumption (lower power bill, takes up less power on the circuit), takes up less space, ability to OC to 1.5 in proper environment.
