I'm a T-6 IP with a background in C-130s and KC-135s. I used Accessible Aviation in Columbus, MS and recommend them. It cost about $3000 and took 4 days. The owner, Carl, is a retired USAF fighter pilot. He'll make sure you're ready for your checkride, and if you're not, he'll tell you. no big deal, pay for a couple more hours in a Seneca. I felt ready for my check after two rides, and the checkride went well. No surprises.
