Can anyone tell me what kind of forge I can get for less than $600? Or is there a belt grinder for around the same price? I've got about $600 to dump into knife making and can't decide what to do. I have a belt grinder now but it's a 1 by 42", need something better. Up until now I have used this grinder and heat treated in my wood stove until the magnet didn't stick etc.. Any feedback would be appreciated.
