I have a Beigle/Bryant ScopeSaver with laptop extension for sale (bought about 3 years ago). It is in good condition with a few paint blemishes in the area to which the scope attaches. This is a great accessory - I'm selling it only because I recently sold my LX-200 mount.
The combination of ScopeSaver and laptop extension costs $139 if you buy it new from Beigle/Bryant. I am selling mine for $50 (+ shipping).
