At one time, he had AGS Counter top vacuum tumblers that he had accquired in a one time purchase that were being offered at a special price of $39.99. I just checked his website, and they are no longer listed as in stock, so I would take that to mean they are all gone. You might try and PM him here or email via the company website to see if he has a couple left that are not listed. His SMF username is "TJOHNSON" and this is his profile link:

I bought one and they work great for jerky. It's a heavy duty canister that has a manual hand pump to create the vacuum and then the canister, meat and marinade rotate in the base. It basically accelerates the process of getting the marinade into the cut jerky slices. If you have a foodsaver and one of their vacuum canisters you can sort of do the same thing, just have to shake to simulate the rotation. But vacuum devices do help infuse the marinade into the cut meat very quickly.
