Thanks!
I understand that it's difficult to say, my first idea was somewhere around some $7 or $8 to make it worthwhile. I saw that Tom Tullis charges $25 for his profile prints but they are twice as big and Tom Tullis is, well, Tom Tullis and I wound't want to compare myself to him...
Erich: I'm thinking A4 size, which is roughly 20x30cm's, that's what my profiles are made for. Bigger than that and I'd have to start from scratch. I've only got 109's so far, but I've learned so much doing these that I think it would be much easier to go to other aircraft now compared to when I started the 109.
