I highly recommend
www.betcoinsports.com , have gambled with them on and off a bit over the last 6months and had pretty decent luck there (unfortunately my luck is terrible everywhere else). Deposits do require 1 confirmation, and Withdrawals arn't always automatic so can take a few hours but mine have usually processed within 15minutes or so.
They offer blackjack/slots/tablegames + sportsbook and poker.
Their email support are very helpful and usually reply pretty fast (i believe they have 24-7 support.)
Probably one of the few gambling sites where i feel like everything is against me.
