The 5″ f/5 has gone, but the 145mm f/6.3 refractor and EQ5 are available. The 6″ if a bit out of collimation and needs a bit of work. The EQ5 is manual only, no motors. It has counterweights for the 145mm. There is a 2″ diagonal and 2″ Superview 30mm eyepiece.
The refactor in it’s current state, with diagonal and eyepiece is maybe $300, the mount $400. So $700 for both.
