I would recommend to buy used cartridges from ebay to get buyers protection for those who’re not sure about the seller reputation. The price may be 15% higher than in the private agon listings, but at least there is no chance you will be ripped-off.
Why not ask the seller about suspension condition or to ask for additional pictures of everything if there is no clear statement in the listing? I would avoid the oldschool sellers who can’t even take a good pictures of the cartridge, cantilever, stylus tip.
But there is no reason to avoid used cartridges!
As Halcro said:
I’ve had many more disappointments with ’new’’ cartridges and it would take some serious word-of-mouth for me to outlay again for a ’new’ current model.
Exactly, that’s why buying vintage cartridges (NOS or Used) is great experience compared to overpriced new high-end models. Most of us buyin and selling cartridges, i do that just to try something different searching for "my sound". I hardly imagine someone trying to full people on ebay, bacause it’s a nightmare for the seller if the buyer is not happy about purchase. Pretty easy.
