Does anyone use one of these or have they in the past?
Yes, a few years ago.
What do you or did you like about it?
It was quiet.
What don't or didn't you like about it?
It was built wrong. Turn it 90 degrees, extend one track, add a crank arm to oscillate one track to squeeze, then release. Did a poor job of removing honey. Did not remove wax from extracted honey, just uncappings. Needed attention at end of day(shut down procedure). Cook and Beales did a much better job, but was noisy.
What is a used one worth in good condition?
Scrap price(what it's weight is worth in scrap), unless you care to rework it.
I do however believe that the concept has merit, just that this was a poor embodiment of the concept. Mr. Fager did the best he could with what he had available. I believe there is a market for a similar device, if it could produce results as good as a Cook and Beales, but without the noise and power failure worries.
