Finally found a pretty good one at Fantes. For $19.99, it came with two stainless steel drums (medium & fine). Used it today with the medium drum to grind hazel nuts for Lebkuchen. It did a nice job. Based on my last two sets of purchases from Fantes, I have them on my list of great vendors (fair prices. good selection, prompt shipment).
I think I found them based on Michael of Fort Worth's comments about wooden spoons.
