OptionsHouse minimum - $1,000 for cash account ($2,000 for margin)
commissions: $5 for 5 contracts or $8.95 + .15 per contract
Very cost effective so it is good for the beginner following this board who doesn't want to invest a lot of cash.
If you have over $10,000 to start with I also recommend Interactive Brokers, though the platform isn't as intuitive, it is probably the most powerful in the industry, their routing is second to none, and they are a professional service. Though they do charge for modifying orders so it is something to be aware of. Their commissions vary based on volume.

If you want good tools I would suggest TD Ameritrade. They are slightly more expensive but their Think-or-swim platform is really intuitive and their other tools are great too. There is no account minimum but funding for a margin account is $2,000 as almost all brokers are. Their commissions are $9.95 per ticket + .65 per contract.
