Gambling site with better odds with larger bets?

[Elwar]

Just wondering if there are any betting sites where your odds get better the higher your bet.

Say a 50:50 game with house edge of 2% for a 1 BTC bet while it is closer to 1% for a 10 BTC bet or .1% for 100 BTC bet.

I only know of SatoshiDICE and do not gamble so this is more research than anything.

Pretty neat idea. 100 BTC bets at .1% house edge though.. Doubt that'd be very feasible for anyone who's looking to make a consistent profit. There'd be some insane variance on that I'd say
