Try a 1TH instead. Because its more likely you'll be struck by lightning multiple times over hitting a block.
Well that's not really true. His chances of hitting a block in a month of mining is about 1 in 14. But those still aren't good enough odds for me to recommend solo mining.
This is my thoughs, I might be wrong, but this is my math
Lets say 12/24 months pool mining vs 12.24 months solo
Pool mining
12 months = 7 BTC, 7 * $375 = $2625(profit)
24 months = 10 BTC, 10 * $375 = $3750(profit)
Solo Mining
12 months = 25BTC * $375 = $9375(profit)
24 months = 25BTC * $375 = $9375(profit)
36 months found a block still make profit (may be at this time btc price is sky rocket)
