Tim,
As the other guys are saying I use gas, but I keep a couple of nice coal forges too. I enjoy using coal. So, if that's what you like, then go for it. It's hard to say if the forge was worth it, but if it's in good shape, I would say it is. The last one I bought, I got at an auction for $66 dollars and it's the best I have seen. All I can say is I got a good deal. I tightened it up and painted it and it's worth a few hundred now. The one you bought, probably will be easy to load and unload, which can be a plus. It really depends on your situation. I do a lot of demos and coal works well for that in "old timey" stuff. You know. If I have to try to get something made quick, gas is the way I do it. Lin
