where can one go to find a decent list of what used telescopes are worth, or at least currently bringing.

Does anyone remember this scope? It was called the "sky challenger". Purchased in 1975 new, it came with a 2" focuser, extra heavy duty mount and clock drive and 8x50 finder. Looking for ideas on how to replace the teflon bearings with roller bearings. this model was the 6" f/8 model.
