Help me find a good vacuum pump and enclosure on ebay.

So, I’ve always enjoyed experiments where people throw things in a glass container and turn on a vacuum pump, I’m wondering if I can get a good combination of whatever these are on ebay, I’m not really sure what you would call the set.

anyways I don’t know the price range these things go for either, so I figure maybe you guys can find some good ones and help me get an idea of the price range
