Online tax tools

Hi, new here. Just fishing around to see what people might have to say about Taxbrain. I'm doing my taxes myself and am looking for the latest and greatest means of e-filing and these guys seem to be it. No software downloads, real-time chat support, refund advance, all the bells and whistles. I've done the Turbo-tax thing in years past but Taxbrain seems to be the tool of the moment. Anyone use it or planning to? Yes, I realize I'm last minute... gonna owe and plan to make em wait for it until the bitter end.

Had to share... just finished my taxes last night and thanks to Taxbrain I am actually getting a return. I'm wishing I'd done my taxes earlier now. Happy Friday the 13th!
