you know
i have a great appreciation for older stainz, even the clams (time consuming to open and lube /clean) -rugged, metal rods etc-simple reliable
i have many-some i bought only a few years ago used, and i had to rebuild a couple, gears and motors, water damage and overload
sharing my POV only
price is everything, as well as condition
pristine might bring some return
as might an interesting color
many parts are in fact expensive
and even if advertised as having new this or that, its still 'used'
and while i have a love for older LGB, just because i appreciate the history and the fact that its been my play toy since about 1986
and the evolution and older models have some nostalgia for me
i actually find i like the new Stainz's best, even with the plastic rods , as they have nicer valve assembly, and many other nice features including the switch, white lights, cab light and modern plug
my point is i think you may find its hard to turn a profit-
the fact is used is used, and most wont pay very much if theyre in the hobby -especially for the wonderful (but ubiquitous) stainz-they are green and red, common, plain featured, and small-and many do not appreciate these aspects -
what i would pay for, up to 350-400 US i think, would be an Uber Stainz, synch sound and smoke, great paint, constant lighting -just FYI
i mention this as it may be an avenue for a greater margin
