I've built a bunch of stuff with my HF 110 wire feed and hydraulic pipe bender. As was said before, it's all in the prep. I don't do enough welding to make it worth the $$ to get a really good welder, so my little wire feed serves my purpose. The hydraulic pipe bender takes a bit more time to line everything up, check, double check and triple check, but when its all done, the end product is about the same.
