I'm sure Dirk's a good guy and thus I did not want to identify the seller so that the issue of "etiquette" would remain unburdened by personal feelings. It's is not my intent to litigate this issue publicly on the Registry.

That said, not sure what Dirk means about buyer "asking for lower and even lower price." I made an offer, he agreed, I paid by Paypal Friends. Bad move #1. When I went to my local Post Office to complain about damage, they said I needed to show it to them on the day I picked it up, which I did not. Bad move #2. I should have sked that package be insured for value of sale. I did not. Bad move #3. So i bear some blame and willing to take a financial hit as a result - partial refund, etc. Not aware that Dirk had found a replacement lens. if there is another lens to match the one that was broken, I'll take it and pay reasonable cost.

This thread has opened my eyes to a number of issues that buyers and sellers should clarify before a deal is done. Cheers to all.
