I use hold'em/tournament indicator along with HUD.. they work very well in tandem with each other. TI keeps track of your M as well which is very nice. Its a smooth program with great customer service as well.

One of the cute features is the "nuts alert". I love that it gives instant pot odds.

I would advise learning to calculate all of this crap yourself though, then just use the calculator when multi tabling for speed sake.
