I bought one like this on Ebay. It works great. The door can be a little sticky sometimes, but for the price I can live with it. It only does 5 or so at a time, but again, you get what you pay for.
Okay I dug this out of the shed, its a Model DE-4 from UVP, man date May 1996, looks like the one in the picture, just a little more yellowed plastic, I found this site about it???
