Just so you know, I skipped out of Scottrade due to problems buying EVFL, and jumped to etrade. Haven't had a problem since. Nibbled a bit today, in fact. IMHO, at these prices this is worth a small risk. (Not more than you can afford to lose,of course.)
I use TD Ameritrade, but Zecco has great prices and ppl here say good thing about Zecco. I hear some good but mostely bad about Scottrade but as far as I'm concerned they are all good until you use them and know for yourself.
I might consider checking Zecco out later this year.
