Depends what you want. If you want a Bulldog or Chippy for example, you have to buy used. Then the problems start.
If you want new, you are almost limited to microlights, ultralights etc (unless you are very rich). All those have many restrictions as to what you can to do with the aeroplane.
So that is the rub; what do you want to use it for; a bimble, aeros, touring?
Buying new also has problems. You may be subjected to moveable exchange rates, money up front, collection from Italy etc (not too easy in winter).
It's a very complex subject!
