I recently started an optionsHouse account to check it out, and am reaching out to see what others' opinions are about the site.
My pros:
Pretty interface (hey, visual UI is very important)
Cheap
Maggie in support (cute voice, and I have her direct number instead of an operator pool)
My cons:
The tools seem a little underdeveloped, though I do prefer to spread my trust over multiple sites anyway
Death by ACH (up to a WEEK to transfer funds from BAC checking!)
Even slower account setup (2-3 weeks)
Any problems with phantom orders? I suspect they play their dirty game on the ACH float instead of "mistakes."
