re: Poker & Tracking programs
HEM has a 15-day trial I believe. I've used both PT3 and HEM and I much prefer HEM. You can buy the small stakes HEM (up to 50NL, $1 Limit, and $22 tourney) for $55 or the Pro version for $80. You can upgrade from small stakes to Pro later for $30. They also offer an Omaha add-on and a Table Scanner add-on (which is new and still being ironed out), both have free trials also.
If you play seriously, even at the micro stakes, having a good HUD and good analysis tools for finding your own leaks is well worth the very minor cost -- you can easily use these tools to improve your game and increase your poker revenue such that they pay for themselves in no time. Just a couple of good fish pots in 50NL will pay for them.
