The prices are quite astronomical.
Allen, I'd love to see you get back into some models instead of these videos. I watch about 3 minutes , then get bored. I study you model work, and your CAD work. Even is you just produced CAD models., that would be quite interesting, and we have a section for that. I am building an work bench, and am trying to get the nerve up to build your Savoia S-21. I have two copies printed out which came out perfectly.
