I've been finding that I need to stay away from the larger sized fountain pens ... I just don't have the equipment to make them without taking chances. Once I get a half inch #1MT drill chuck for my lathe, I should be able to drill them OK, but for now I'm limited to 10mm.
In this range, I've found that PSI offers 3 kits that I can make.
Traditional (10mm tubes) ... these come with metal plated finial post and cap, only 24kt gold finish. These appear to be the "snap cap" design. Prices are reasonable to work with, at around 9 dollars a kit when not on sale (currently $7.85). The gold colored nib looks nice, too, but there appears to be a largish piece of plastic between nib and body.
Classic (10mm tubes) ... these come with a plastic finial and end cap, but the cap is posted with a screw attachment. Prices here are a bit higher, at around 11 dollars fr 24kt gold and the gold and enamel style. Chrome comes in at 10 dollars. This style also appears to have a large plastic part between nib and body.
Classic Elite 2 (10mm tubes) ... These come with a design that appears to be more of a metal based construction, with metal in the finial, cap, and nib area, though there are small sections of plastic here and there. Most notably, plastic threads. These are a bit pricier at 13 - 14 dollars for a 24kt gold and a 24kt gold + gunmetal design.
I think I'm gonna go with the Classic Elite 2 and see how well they turn out. Good luck to you guys!
