Your goal of flying warbirds is a worthy one. However, I'd suggest you start looking right now. H9 has provided for that market for years. Try to find one of them today. Great Planes the same. Phoenix is worth a look but seems to be going the way of the other two.
Speaking of Phoenix, you might consider the military trainer: PC-9
