The two brokers I recommend from a professional standpoint are Interactive Brokers and Optionshouse. I would suggest opening up an account with OH and using tools from a different broker (for instance TOS by TD Ameritrade). OH's tools aren't great, but their commissions are fantastic especially when buying large amounts of OTM/low priced contracts. Other than that just read reviews of the various brokers and choose which one best suits you, but I feel confident in both of those brokers.
