What’s the value Labs599 TX-500 qrp station

[KN6YDC]

I’ve had these about a year, never used them.
All purchased separately I have a labs599 TX-500, I’ve used it very little, add to that I have a PA500 60 watt amplifier and tuner made to work with the TX-500 and with them is a BA500 battery in the same form factor as the TX-500 and PA500. The QRP store advertises these as a set for 3600, it took me 10 months to finally get the amp and over a year for the battery. Since I’ve had these for a while with no use I’m considering letting them go, they are in pristine condition. I don’t want to separate them but sell as a set.
