i am new in poker games and not really familiar with the rules. So how poker tools can help me to improve my poker games?

you can get free poker tracker 3 if you sign up to titan with pokertracker.com
clear the sing up bonus at titan and then you can go and play anywhere you want.
I have recently bought Holdem Manager to give it a try. Used PT2 before. Played only 10k hands with HEM soo for now i am satisfyed with it.
Cant sey much about PT3, but when I was hasitating which one to choose PT3 had some update issues (was recently relased), soo I went for HEM.

what is the going cost of a good poker tracker? Can you just get a HUD, or are they tight in?

PokerTracker 3 is a suite of online poker tools that track, analyze, and help you improve your poker game whether you are playing Texas Holdem or Omaha. It is the single most important piece of online poker software that every poker player must have to be successful. PokerTracker imports the hand histories that poker sites write to your computer. It then parses the hands and stores poker statistics about the hands into a local database so that you can look at every possible angle of both your and your opponents' poker game.

Get PT3 (Poker Tracker 3) or HEM (Holdem Manager). Both very good poker HUDs / Trackers and they come with a quite long trial so you can try it out for free
Holdem Manager is $55 for small stakes version and Poker Tracker 3 is $45 for small stakes also. I suggest that you try out both programs and find the one that suits you.
