As a welder/fabricator I can tell you that price is very reasonable. I couldn't make one that nice for twice the price.... but also pretty pricy for what it is.
Nice, then you can mount up your $40 POS Harbor Freight vise and hope that the casting isn't just crappy enough to crack on you as you put that last quarter turn on the handle trying to press in a u-joint cap in the middle of nowhere. It happened to me in a buddy's garage using one of their "too cheap to be true" bench vises, so for me it's not just a "what if?"
I caught a lot of **** from a friend when I bought one at the sand sport super show. Two years latter and I have to say it is one of the best purchases ever. I use it a lot. It is really well built. I like having the nut instead of the normal slide bar. I own a hi-lift also and will not detract from it's usefulness, but when you bend a tie rod, get a fiberglass flag on a quad mound stuck, or need to hold something to cut or weld nothing beats a good vice. Excellent product highly recommend it. I build my M1010 using that same vice mounted in the hitch saved time not having to run into the garage and back.Pretty handy, but I wouldn't spend that much on such a rarely used item. Pretty sure you could do a lot of that stuff with a hi-lift?
