I just flew a Texan in Florida. It was a free bonus ride froo the graduates of Tom Reilly's Warbirds Restoration School (in addition to a ride in "Panchito", a B25J Mitchell). They normal charge is around $300/hour, or $450/hour for the full aerobatic schtick.
They had some P-51 there as well, I don;t know an exact price, but I think it is around $600-700/hour.
According to Tom Reilly, an hour of flight for the B25J is $750. It is the owner cost, not the rental fee.
I would strongly recommend a Texan flight. This plane is wonderful to fly.
