Hello John, I too have a beautiful 6600 and TGXL I would like to sell, but after posting here I received no queries. I think folks are electing to spend twice the money and buy the 8600 due to the threat of obsolescence perhaps (parts availability) and the lure of potential new features offered for the later models.
Not just Flex .. I had listed my like-new Collins S-line and Drake C-line radios, all mint condition, and the only interest I garnered were ridiculously low offers. Laughable .. and disappointing.
Fingers crossed that you find a buyer ..

Daniel- I saw where someone about gave away a 6600M for $2800. Flex is selling 6600s for $3200 with a warranty. Mine has age on its. side, I suppose. It's less than 2 years old.
