I've always been a fan of the Bader style grinders myself. I build my own because I'm picky and want everything exactly how I like it, but if I needed a new grinder tomorrow, I'd order a B3 without question.
Bader also makes the best contact wheels I've used. Boring out the center hole and installing my own bearings, I can get one running with a reasonable bit less runout (20-30 thou) than a Beaumont wheel.
