What's the market these days for NOS 70's/80's cartridges and/or tonearms?

Not much left. I bought it all from Russian time traveler.

The market is crazy for everything vintage and NOS. You named some brands, right, a well known brands normally cost more than unknown (and even better quality) brands. The prices going up constantly. Same about rare records, absolutely insane prices on auctions for rare original vinyl.

Last week I was reading about Nakamichi decks (Dragon, RX505 or RX202 etc), reading old posts on various forums I realized that probably I have missed the train (10-15 years ago). It’s unbelievable, the prices today are crazy! Even for cassette tapes the prices are very high. So the deck you expected to buy just for fun (because it’s cool) will cost nearly $2000.

Same about vintage cartridges and tonearms. Sometimes it’s better to make your own discoveries and grab them before the price went crazy in the next 5 years.

@chakster , Most of the NOS cartridges are gone no? 

@mijostyn  No, I did not buy all of them yet, but learned which of them can be ignored. 

I have a NOS Shure V15-mk5mr in original box plus a NIB Jico replacement stylus. Wonder what these will be worth two decades from now? So far I have held off from using this V15! I have plenty of other cartridges on hand. Using the NOS Shure can only reduce its future monetary. value.
