The freerolls on fulltilt are actually pretty easy. Lots of people, time consuming, and not that much money to win, but it is a good way to start IMO.
Beats depositing 50$, lose, deposit 100$ lose and repeat a couple of times.
And about playing freerolls would be bad for your game. If you have any talent u will learn to adapt to real buy-ins, or cashgames in no time. Especially if you are prepared to read an article or two.
