Software-- Outs, odds, calculator

[mandel]

What program would you recommend me for calculating quick the outs, odds, pot odds, probabilities... etc?
Texas calculatem?
Is there any program for free?
Do they work with several tables?

And for opponents tendencies i use Poket Tracker and Gametime? Is there any better option? (I'd love to have one with %checkraises and %bluffs)
