[Elecraft] Fair K3 selling price?

[Scott Manthe]

Hello fellow Elecrafters,
I'm getting ready to sell my rarely used K3 and am having a tough time 
figuring out a fair price to ask for it. It is an unmodified original 
K3/100, with the KSYN3 original synth, with the KFL3B-FM, KFL3A-6K, 
KF3A-2.7K, KFL-500Hz and KFL3A-200Hz roofing filters installed. It also 
has the KBP3 Rev A general coverage receive board, the KIO3 and the KXV3 
IF in/out board. I also have an uninstalled KRX3, with the KFL3B-FM, 
KFL3A-2.7K, and KFL3A-500Hz roofing filters installed, and the original 
KSYN3 synth. Everything works fine and is in great shape, but I have no 
idea how to price it. Any advice would be appreciated.

73,
