Well, the Paul Blymer SU26 certainly looks to me like something that I would - ah.. attempt to put together myself. The price seems reasonable and it looks like something pretty solid. Someone that has experience with it may be able to give you more, but with lack of that, I would get one just to play with. The 9mm depron models look pretty solid. And, with some spare Depron, well, perhaps accidents can be repaired fairly easily.
