It's a crapshoot. Literally. You might get an excellent set of bellows, and you might get junk, and you might get something in-between. The only direct experience I have is installing an epay bellows on a Technika belonging to a friend; the replacement was about 14" in length, which is 2+ inches too short, yet they were so thick that the camera wouldn't close with them installed.
