Best site for HU 4 PPL SHOOUTOUTS?

Hi guys;

I was interested to know if you know of any good poker sites that host heads up shootout games, the once with 4 people...! and has a many games to offer in that kind of shootouts...

I know about full tilt and pokerstars, but I am looking for sites with more different limits and people playing those kind of heads up games...! I am looking for particular those games with 4 people... you play 1st heads up, if you win, you play the other player who wins the other table...and winner take all...!

If you do, every link would be greatly appreciated...!!

Thank you.

ps and Full Tilt Poker are the best u going to get with those structures IMO
i would personally suggest ps due to the fact they have 32 person, 16 person ,8 person, and 4 person and 2 person hu games at many stakes with many different games available
they also have heads up tournies
