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.

I think Swampwalder's advice is spot on. That is what I did and have been very happy with this decision. Eventually, due to my own carelessness, I had the cartridge sent to soundsmith for a new cantlever/tip (bent it) and that was also an excellent decision.
No, I don't have to get them rebuilt. They work great as is. This idea of suspensions failing is non existent in my experience and fostered by those who do not know better, or have some agenda.

But, hey, buy new, and sell to me in a couple of years.
It is a gamble and would be a hit or miss.
I've bought 5 or so used cartridges/stylus in the past 10 years, and 4 were pretty good and 1 was defective. Still, I paid for less than a third of the new price for each, so it worked for me.
The most important thing is to buying one from an honest and reputable seller.
Those of us who buy second hand know, or should know, what we are doing, risking. As Ilcho says, the rewards can be very great indeed, 33% or less, of the retail price, for a cartridge not even run in yet. That's worth a bit of a gamble, for me anyway. If it's not worth the risk to you, that's fine too. More chance for me to snap up a bargain
