Poker Software Tools

Finally, I’m thinking to buy an opponent tracker/database. These software keep track of how other players play and give info on their styles.

I’d prefer for this type of program to have an HUD display and offer advice on how to play against opponents.

This is a list of the programs I’m aware of:
Smart Buddy
Poker Office
Hold Em Indicator
Poker Edge
Poker Crusher
Poker Spy
Poker Charts (web-based)
Poker Sherlock
Poker Tracker

Thanks for the help!
