Finally found a good used Bader BII after looking for about 3 months. Should arrive in a week or two. I need to order some belts and was wondering what grits I should get to start. I was thinking 50, 120, 220 and 400. Is this OK for a starting selection of grits? Where can I get the best price on grinding belts? What type of abrasive or brand of belt should I get? Any help would be appreciated. Ken
