I have a Grizzly and, for me, its the appropriate machine for the money. Reading Tracy's post, I have to agree with him 100%. In fact, I think that's the best description of what level of equipment to buy that I ever seen, and you could apply it to any equipment, not just a grinder.
As for the 72" vs 48" lengths, it's not just the amount of grit that makes the difference. I did some consulting years ago for a company that makes sandpaper. The "killer" for sandpaper is heat. The longer belt allows heat dissipation and keeps the adhesive from breaking down as quickly. The grit is harder than steel, so it's not wearing down; it's being stripped off as the adhesive goes.
