I am surprised that helium reclamation pumps are not beginning to appear as surplus. We are several (technological) generations into the period where supercooled MRI magnets are present in every town over 10,000 population in the US. Medical MRI has been in use for around 20 yrs, and though the demand for used equipment resold into less affluent markets hasn't probably been saturated, some of the squeaky little buggers should begin to turn up just because of their age.
