I'm still very dubious this will actually make any profit. At the current rate of difficulty increase (may was 74k low and june was 124k low) 32 chips, 9 g/hs would make generally nothing later in the year.... anyone else done the math?
How about preventing a 51% attack? I'm sure that is a good cause, no? Recent developments with FTC are indicating it was 51% attacked. Some people are speculating that LTC will be next. purchasing even 9.2gh/s will help to secure the bitcoin network and your bitcoins.
