I bought a single bend for $52, I can get 12 good 44" belt blanks and some scrap for small projects and practice out of it, that comes out to just over $5 per complete belt (econo buckle, line 16 snaps, and a keeper). I sell them for $30 each (cause my skill level is still pretty low), it takes me anywhere from 2 to as much as 7 hours so far depending on what I'm carving. So IMO it's a good investment. It just depends on how much you think your time is worth.
