Ham Radio and Astronomy - Swap Potential?

[N4TT]

Looking for some advice. I have a Flex 6700 that I'd like to sell or trade. I was considering holding out for the release of the K4HD but I've also enjoyed astronomy in the past and wonder if there's any amateur astronomers out there that could suggest an approach. My 6700 was purchased new in Feb 2019, has the GPSDO option and includes the Maestro B. I've paid for the 3.x upgrade but it is not installed.

Would Cloudy Nights or something like that be more appropriate for posting a trade like this?

73,
