@twocorgis tried to buy one and went through two or three samples before he gave up and returned the last one. I think they were all fit and finish type issues on what was being sold as a new instrument.
I spent many years thinking a vintage M85 was a Holy Grail. I tired and missed out on a couple that sold for over $3K. When I finally got to play a 1970 M85 I (belonging to
@The Guilds of Grot - see my avatar) I realized that there was very little it could do, sonically especially, that my '67 Starfire didn't already do. It became less of an obsession although I still have First Dibs on Grots.
@Happy Face has a vintage M85 II. He is less enamored of Starfires so he is likely to have different opinion about what is a viable alternative to a M85.
@mavuser has a GSR M-85 II.
To the question, last I checked the Newark Street M85 I was no longer available. So it would be a good choice but also is competing with the original Newark Street Starfire I with Bisonic which is only available used. The current Starfire with a P bass style PU is certainly a contender if you want Guild and short scale and can be flexible about a Bisonic.
