This miner currently makes $30 a day. Next batch will ship out in 6 weeks (42 days)

$30 a day * 42 days = $1260

1260 (mining profit) + 930 (miner cost) = $2190.

Assuming mining profits don't go down (which they will) you're selling at a break even point.

It makes more sense to wait for the next bath than to buy yours.

I'll offer $1500
