How hard is it to find a Nathan, Detroit, Edna, or any other type of hydrostatic lubricator? A four feed would be preferable to a three feed hydrostatic. My group is considering the purchase of one, but only for the right price. This also just serves as a personal curiosity question.

A Detroit 22, New in the box? $5000 apparently. See below:

Thanks Joe! That is really nice, but we are definitely happy to restore one if it means that there is a lower price! We have to be able to say we have some pride in its operation!
