I had several similar tools, from Harbor Freight. Only used once or twice, then they followed my younger son, and ran away from home. Worked well. They are listed at $21.99 for the 18" model, and less as the sizes go down. I don't normally use tools like that, so if a need for one arises again, may well just make a cam clamp.
I have never had a Harbor Freight tool break on me. My sons wind up taking them, and the first I know about it is when I need to use one of the tools. So I buy another tool. Now "they" have broken tools. Sometimes they break tools that should not have broken even. But I can truthfully say, I have never broken a Harbor Freight tool.

Of course I'm not busy, I did it right the first time.
Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
