Can anyone tell me where to get one of these??

The one you have looks good. There's a guy in Fort Worth that I've used for a long time that refurbishes these things for about $50.00, IIRC. It's called Mr. G's. However, you need to check with him to see if he has one on the shelf. Right now, he's without a vacuum metalizer and a painter. Essentially he's selling off inventory.
