Cost isn't the problem it's the quality and usability of the one they have. I have the cheap one and modded it over the years but would love one that you sit on and you foot opens and closes it not a bolt something that uses a strap to the latching mechanism and it latched with your right foot. Plus the clamp can rotate maybe. There's a good pattern in a old public domain boo k for a farmer or ranchers that do their own leather repairs, build all these devices for around the place.
