Open a NetBank MMA and get $75 if you have an average balance of at least $1000 for 30 days. Fees to note:

+ $5/mo fee if account balance goes below $500
+ $25 fee if you close account before 6mos
+ $7.50 fee for closing account after 6mos (you still come out way ahead if you deposit $1000, get the $75, and earn a 3.52% APY)
