sorry, I can't add to the knowledge bucket for Jukis
but as an alternative thought, you might look for a Singer 301 or 404. Light, workhorse, fun to own, and you can do the service (what little there is) yourself. It is also a fun search
and singer cabinets are fairly easy to find and cost nearly nothing... they are 50-60 years old and will no doubt last another 150 years.
