Does anyone have experience with seller Kron on cartridges?

Carter, look at the whole list the Audio-Technica authorized dealers in the USA, i'm pretty sure some of them still have discontinued ART9 with discount, but make sure to buy from authorized dealer if you want to be able to get the new one when the stylus will be worn out. 

You can also buy a brand new ART9 XI or XA version from Audio-Technica directly (online with warranty) here. 

Paypal protect buyer with full refund even if the item lost in transit between seller and buyer. 

If you will pay by wire transfer you have zero protection, if it will be your first purchase from no matter what seller, my advice is to stick with paypal only (not "family and friends" or "gift", but "goods" only) with full buyers protection guaranteed.

Everyone can make a mistake, you will pay for it if you’re not protected.
It can be a postman or seller, we heard all those stories here on audiogon many times.

If someone else has bought anything from the same seller how can it help with your case ?

Stay protected by paypal buyer protection, this is how it should be for the first transaction at least.

definitely, especially for the first purchase

What cartridges are you buying fro him? 
An old nos or vintage or grey market products ?
