I tried it a few years ago and had an absolute blast. There are a number of organizations that offer similar programs, although they seem to use different airplanes (Air Combat uses Saia-Marchetti's and I know of two others that use T-6's and Extra's).
Most of them go "on tour" around the US at different parts of the year, so there ought to be one fairly close to you at some point. Unfortunately they all cost approximately the same but IMHO it's worth it if you can possibly afford it, especially if you're a die-hard AH/WWII aviation fan.
