Tiger Moth,
Have you ever thought about microlights? I've only had two trial lessons, but it was enough to know that they definitely give you hands-on flying, and I gather that's what you're into. They're cheaper, you won't need a CPL as there's no such thing, and I gather instructors get paid a little better. I don't know the ins and out of this, but there are people on PPRuNe who do (Genghis the Engineer, where are you?). They'll probably read it if you post this on the Private Flying forum.
I know you've set your heart on flying Tiger Moths, but there's nothing to stop you doing both eventually, and this might be a practical solution to your problem.
