Greg,
I couldnt agree with you more.
When I stopped going to the accountant, and started using turbotax, I saw no difference in taxes paid.
When I went to an accountant for the one time event after using turbotax, he did not see any other deductions to go after, even with our interview.
If your a regular Joe, turbotax should work for you, if you really want to push the envelope, perhaps an accountant will be able to help.
(by the way I switched accountants for that one time event).
