Direct-access firm MB Trading. Equities $0.01 per share, minimum $1.00. Options $1 each. Excellent customer service, free charting program (although very basic), integrated trading with good charting programs, and very reliable. You can check them out anywhere in the Net to see they're legitimate (how they keep commission so low, without making a market and eating the spread, I don't know). I've traded with them for years, no complaints.
