if you're the type that builds or fixes things regularly, then an ironworker would be one of the handiest pieces of machinery around. problem is, unless you use one every day, it's not really a cost effective tool. sure there are some old used ones out there for cheap money, but they are generally massive, and myself, i don't have the floor space to donate to one. not to mention, the good deals i see are usually 2000 miles away or more, so even going to look at it is not practical, let alone bringing it home. there are nice small ones geared toward home shop size operations, but they are all newer and will generally run you several thousand dollars with tooling.
the good thing here is that an ironworker is really not much more than a glorified shop press. you can use most any shop press and build/buy dies that will make it punch, bend, and shear metal like an ironworker. the limit is the capacity of the hydraulics. you can sometimes find used ironworker tooling on places like ebay for cheap prices, and rework if to fit into your shop press.
I bought a 40T iron worker for $100. They can be had reasonably if you keep an eye out and are patient.
