Random Hand Calulator

[ohiou]

I know this has been posted before but I couldn't find anything on the search.

I am looking for an online random hand generator and odds calculator that will let me run a selected starting hold em hand versus any number of opponents with random cards.

I've searched on-line and can't find anything either.

For the math people in the group, specifically I am wondering what the pre-flop and post-flop odds of AA winning versus 3-5 random hands. Any help is much appreciated. Thanks
