I have a custom machined Borg 115mm tube (length cut for 125ED 6.4) with an AP 2.7" focuser. Tube has minor dings, focuser is as new. Asking $340 obo. The AP focuser itself is worth $390! Makes finding focus much easier when you have heavy items attached like a 2" diagonal and EP's or CCD cameras. Only adds about 3 lbs to the total weight and moves the balancing point forward!
I also have a Borg case for the 125ED 6.4 that is in good condition that I'll let go for $170 obo. This case is $249 new from Hutech.
