For me the best is the 90-man $1. +.25 on FullTilt. It's double stack (3k starting chips), 10-minute blinds, and it pays 18 places.
The double stack provides some cushion for dealing with the early stage idiots and their donk-outs, and 10 minute blinds means you can sit back & wait for a good hand.
I'll have to try the 90-mans at
pokerstars, thanks for the tip, jordanbillie!
Then there's the
bodog beginner tourneys where the top 5 get paid. If you finish 5th you lose the rake. Pretty easy money, if somewhat of a grind. These are really cash cows (shhh).
