about those jobo compatable chinese precessors
Found group here operating out of xi'an university, They make processors as seenhere and here and here and here. Prices and stats are given from 9200rmb for the big one (heating and cooling) 880rmb for the small black and white one. And 4800rmb for the medium one without cooling ability.
They all seem to run using a magnet drive, may be a nuisance to change chemicals with lids coming off etc. I guess they are a bunch of electrical engineers not mechanical ones. If people are interested maybe I can investigate more.
