I've also found a cheap "no-limit tournament" on PokerStars.net. It's on the main lobby's "The Sit And Go Board". Down near the bottom of the board, you'll find a "Hold 'Em Tournament" that has an entry fee of ten cents. This tournament is capped at 360 players and the winner gets $8.50. The other prizes range dowward from $6.00 for second to $.20 cents for 38th spot.
Without a doubt, this is great cheap practice for poker players of any skill level. I've went from 320th position to 43th position in a couple of days.
