Just2Trade appears to have the best margin rates, for what it's worth. <A HREF="http://www.just2trade.com/html/fees.php" target="_blank">http://www.just2trade.com/html/fees.php</A> Also $2.50 trades, options at .60/contract. Not that this is a huge issue for me since I don't make that many trades. Margin rate is more important.
