In my experience at Full Tilt, the $1.25 single-table turbo is your best friend.
Yes, the rake is high, but they're populated almost exclusively by awful players and they're pretty easy to beat. There's loads of loose-passive players that you can value bet to death with your good hands, a few rocks whose blinds you can steal with impunity and way way too many players that will only play fit-or-fold after the flop.
A lot of people seem to be happy with just coming in third too, so often you're good for at least second place if you make it past the bubble. And there are very few players who are skilled at heads up play - most will be either hyper-aggressive, in which case you just need to wait for a decent hand to trap them with, or way too passive, in which case you can steal plenty of pots off them.
The biggest challenge is negotiating the blinds, which can get pretty high towards the end of the game. Mostly it's about picking your spots for a pre-flop shove, though everyone is under the same pressure so sometimes it's possible just to ride them out.
