Upgrading cartridge used or new?


I am in process to upgrade my analog setup starting from replacing my DV 10x5 with an step up one from DV or other make.
My TT rega P5.

On my journey I had hear mixed things about buying used, a much better cartridge or just pay same amount for a brand new lower end one.

Some dealers said you never know the history of a used cartridge, so you must believe the always magic # from the seller of 100 hours on it, plus vinyls condition that was expose to, etc.

While the new even if lower end is a solid secure step.

I would like to hear your exp about buying cartridges on used market.

As always must appreciate all your time to share your comments.

Regards.

Unless you can confirm the history of the cart., I would buy new. Their too easy to damage. At one point I had the 10x5 and upgraded to the low output version of the 20 and found it was a big improvement. Just make sure that your phono pre can handle a low output cart.
I bought a used Dynavector 20 cartridge a few years ago off the Gon. The seller claimed it had very low use. When I installed the cartridge, I found that the suspension was completely collapsed and as a result, the bottom of the cartridge would scrape on the record. I sold it as a damaged cartridge needing a suspension for a song and really lost my shirt on that one. Now, I only buy brand new cartridges.
I've purchased many cartridges over the years, some new, some used. I've never had a bad experience when buying new. I have had good and bad experiences when buying used. Buying used is always a gamble, but even more so with cartridges than typical gear. It's a risk, whether it is worth it or not, only you can answer. Are you feeling lucky??? ;)
Well, I've bought three used cartridges, and I've had nothing but good luck.
All three were in great shape. (Admittedly one was from a friend, so that one might not count.)

My recommendation is to research who you're buying from, (check their feedback and if the post regularly), and speak to them on the phone.

Good luck!
I have had no problem buying used. My best experience, a low hours Koetsu Roseawwod Signature for $950, on the gon. I used it for 3 trouble free years and sold it as used, for only a little less than I paid for it. Clearly there are risks, but that is reflected in the low price for second hand cartridges.
