By the way, I noticed the website was a bit plainer. I contacted the guy through ebay on a best offer auction for a damaged wheel (that had shipping damage around the back side of the radius that a turner might care about, but we wouldn't), and then found his site after looking up the logo on the wheel because someone else bought the damaged wheel before he got to the offer I submitted. I figured if I wasn't buying the wheel listed on ebay, I didn't need to give them 10% of his money, they made their cut on the wheel I missed out on.
From the time I located his website to the time I had a radius wheel (like the ones being discussed) at my doorstep was two days. Since I have a grinder with a 1/2 inch arbor, I figured I'd rather buy a wheel milled to that than have to buy a separate bushing. The only thing I'd choose different on a second purchase is a 180 grit wheel instead of 80, but the grind is not so harsh by any means that you can't use the 80 grit wheel, it's just not necessary to have it that coarse when we do mostly light grinding.
Long story short, the website is legitimate and so is the guy. (I have no affiliation with him and he didn't give me a discount to mention him or anything).
