Not really. It will be whatever is available on Ebay, is complete / working / easy to repair, and of an appropriate size.

There are a couple of different small diffusion pumps that are well suited to fusor use, but they tend to be very expensive if complete / fully functional / seller has any idea what they are selling.


On the other hand, some small, wierd shaped diffusion pumps meant for being integrated into machines (mass spec, gas chromatography, etc) are sometimes available for less than the usual price.

The smallest size of water cooled diffusion pump is often comparatively economical if you can supply water cooling.
