I'm looking for a good penny broker

Question

I thought trying to find a broker would be easy.. well it isn't hard to find one but trying to weed the decent ones out is tricky. I've been watching the pinksheet stocks mostly... so the broker needs to comply with small trades and what not. I've read a few Optionshouse reviews now that outline their trading platform and I think they sound the best fitting but I'm interested to hear of any user experiences?
