Something a little different, a pair of Celestron FirstScope OTAs. In good condition, each OTA has a dovetail block attached for a finder - no finderscope or eyepieces included.
These OTA's are 76mm diameter, 300mm focal length. One has been modified to improve the centering of the secondary in the focuser, and hence improve collimation. In the other unit the modification hasn't been done.
Asking $40 for the pair, pick up only from Maroubra in Sydney.
