The N-reg planes, does that mean the prices tend to be higher?
As I say, my real plan, when the bad weather sets in, is to be further south for that 1/4 of the year. But, the weather is surely going to be a problem, and so an IR makes sense...
I really don't know. There are some advantages and some 'issues' regarding N-reg ownership, so I couldn't guess what effect it would have on price. You can always convert a G-reg to N-reg in the future (I know that
Keef is considering doing this, maybe he can advise?).
The real issue here is that if you get an FAA IR you need to be flying a N-reg aeroplane to use the IR to the full (e.g. access to class-A airspace and the ability to fly IFR abroad). Somehow painting a 'G' on the side of your aeroplane turns you from a trained, competent instrument-rated pilot into a dangerous buffoon...
Oh, and I agree with
Hairyplane, the Robin is an excellent aeroplane. The TB-20 is rather nice too
