I did do a search George. I'm specifically looking for 2" diameter, 80 grit right now and there was a definite dearth of that size other than buying "packages" with one of every size. I used to buy bags of a dozen. I may have to eat the shipping charges from outside of Canada. I'll continue to look. 

Nathan, this is a Taiwan machine that is identical to Jet and others using 5 1/2" sleeves. Mine goes up to 3" diameter spindles.
