Good poker odds calculator?

[bluffme2]

I've been using this one: http://www.cardschat.com/poker-odds-calculator.php
but it is very inconsistent, and maybe incorrect too.

So I've pretty much been calculating odds using my head more or less, applying a crude form of the methods listed in wikipedia
http://en.wikipedia.org/wiki/Draw_%28poker%29#Outs
Is there any calculator that is more reliable?

I like Cardplayer's:

PokerStove is best. But if I am at a computer on which I can go online, but I can not install software, then I use twodimes.net.

Twodimes.net: Poker Odds Calculator

I should also encourage twodimes for non holdem calculations, it's where I go when I want to check a hand from Omaha/Stud/Draw based games.
