Well, if there is any way to squeeze a CBN wheel into the budget, they are the best value for the money, and you will never have to buy another one, never have to true it up, never have to balance it, and never have to clean it up. Cheapest, well, least expensive, are from Ken Rizza at WoodturningWonders, and Dave at D Way, his cost a bit more. They are far better for your V10 than the white or ceramic wheels. It is okay to buy only one, and get a 180 grit, which cuts as fast, or faster than the standard 120 grit wheels. I can't remember about the ceramic types, but think they are in the $80 to $100 range.

I use a 120 grit blue Norton wheel. I have yet to burn one of my good tools on it. It's on a high speed (3450 rpm) grinder too.

Another vote for CBN from Ken Rizza. I splurged on two and am very happy with both the service from Ken and the wheels. Two important features of his wheels are the arbor size which matches the grinder shaft and the self-align washer he sells that perfectly trues up the new wheel. That eliminates all the modifications and adjustments in setting up the wheels. He tossed in a real nice work light and he offers a "club discount."

Peachtree is seling a CBN wheel at the woodworking shows for $120.
The p tree website shows grits of 80 and 180 and dimensions of 8" x 1.5" by 5/8" arbor.
The dimesions won't work for my 8" grinder with a 3/4" arbor.
