I also wasn't a fan of the HF 1x30. Tracking is AWFUL, as Storm Crow says! I went through 3, before I gave up and just bought a better quality 1x30. Did a bunch of blades on that, and tried the craftsman, and honestly, I still use it occasionally, even after I got my pheer, because it's got a longer platen surface area. I generally use it for polishing, but do the occasional work on it. I would probably still be using it if it had a bit more power. Also if I could figure out how to adjust the tracking a bit better.
You can get plenty of belts for the 2x42. I get most of mine from Supergrit. However, you're not going to be doing hollow grinds on it. I also strongly recommend saving up the extra for a real grinder though, despite what I've said, if you're at all serious about knifemaking. Even if you find out in a few years that you don't want to stick with it, a good grinder retains value quite well, especially in comparison to the Craftsman.
