It's early still, but I have been having a bit of success at 1 table SNG's.  I have play 5 on PS ($5)  and 1 on FT ($2 - using my Fantasy Poker League winnings).  I have been in the money 5 of 6 times and have won twice.  Not a bad start.  
I am going to be working with these for a while.  The tight play needed in the early stages of these types of tournaments have been helping top tighten up my ring play too.
