Hmm:
http://bitsolo.net/pool-stats/Found Blocks
None. Currently, no one on Bitsolo has found a Bitcoin block ...
The pool is merge mining NMC coins and has currently found 1 NMC block
Agreed, I don't trust that solo mining pool. It would be VERY easy for the pool operator to simply keep any blocks that are found without paying out anything.
If you don't trust that site, there's also this one:
https://solopool.net/login.phpAt least there's a registration process. Not everything you see is a scam, fellas!

Neither pool has found a block, which makes sense, because most of the users are pointing U2s or block erupters at it. A few TH/s is not going to find a block anytime soon.
