I don't know anything about that machine either but I think I would try to take some thread and scrap fabric to try it out. Maybe if you could find out what size need it takes (and even a bobbin size), you could carry one of those with you too if you happen to have one or both. It's nice to know if the machine works so that you sort of know what you are getting into and whether it's worth it.
But mostly, welcome to the QB. This section is definitely the AA of sewing machines except that we don't get "well", we just find more machines to buy ..... but that does make us happy so no problem!
