Went back and found him today. See still has bushings, can only guess not worth it for him to mess around with the other stuff. Think he has the best video on measuring run out on a lathe ever saw.

Just because PSI does not have an item you need don't be afraid to check with other vendors. Lot of woodturning vendors dropped dead centers from their inventories.
Initially bought my dead center to check head-tail stock alignment, at the time had a lathe with rotating headstock. You can actually use it for checking alignment on any lathe. TBC, not the only thing can use a dead center for if know their limitations.
Many folks here with mini lathes bought dead center from Little Machine Shop years ago too!
