Nok: Which turntable/tonearm exactly would you want to use it on, where are you located and what's your intended budget?
Generally speaking, if you want exactly the same tip/cantilever combination (nude, square-shanked stone with LinearContact (= renamed Shibata) tip on beryllium rod cantilever, BBE (adelcom.net) would still offer the ATN152LP, which is the T4P/P-mount variant of the ATN155LC (so it's compatible, but has a slimmer appearance and no visor guard), but not exactly cheaply prized for not quite US$ 298. Alternatively you might also still be able to get the original ATN155LC, as Goldringstylus(.com.au) would still appear to offer that under their code D1043LC for AU$ 250.
Whereas, if you wouldn't insist on the beryllium rod and would be willing to go for a tapered alu tube instead, you could also go for the current VMN50SH, the not so long discontinued ATN150Sa or the older ATN140LC, which Goldringstylus would also still appear to offer unter their code D1053LC for AU$ 225.
