I am researching the possibility of a price break for a small quantitiy of the STV3 Stainless Steel stuffers that this company sells. I am certain they are probably made in China or elsewhere, and they do have the metal gears. You can purchase these on EBay for $120 US.
If there is an interest I will see if Uniworld will provide a price break for a small quantity of these. If there is any interest please post. I will of course provide updates.
Here's a link to the company: http://uniworldfoodequipments.com/?p=3159
