I bought a pair of near mint JBL L166's a few weeks ago. When they arrived, there was cabinet and grill damage due to insufficient packing and probably poor handling. The shipper has agreed to pay a claim based on value,but thye need me to first prove the value. I was wondering if anyone had an idea as to how to prove the value of these relatively rare speakers. The condition of the pairs I've seen selling on ebay lately are not a good as these which are near almost mint. I would think these would probably fetch $600.00 on ebay if they were to sell there. I may just get a bill of sale from the seller, but beyond that, it's all conjecture. At any rate, if anyone had any ideas how to validate a value, I'd appreciate it. Thanks, Gino
