I have a Tak FS128 and a C14 (black tube, Fastar) OTA that I would like to trade towards a 6" refractor. I would consider AP,Tak or TMB. Of course I would also include some cash along with the OTAs if warranted. Both scopes are in excellent condition both optically and cosmetically. I can send links to some recent images taken by both. I am getting a 12.5 RC, so have little use for the C14.If desired I would include the Fastar system which has never been used and also a Van Slyke Monster III focuser for the C14(excellent!).
