While on the topic of quality, CFF has a limited edition of 80mm f6.9 triplets build around fpl 53, with dedicated field corrector. They come with 2.5" FTF. These are constructed one by one and hand aspherised. There are also still a few 92mm f/6 units available for ordering as far as I know.
There are cheaper options, but you mentioned quality...
EDIT: I think an ultimate around 80mm refractor for imaging would have to be FSQ-85. Another significantly cheaper alternative could be TS-Optics-86SDQ - apparently it has a 60mm corrected circle...
