I am looking for a GOOD used 4.5 or 6 inch Dobsonian scope. I don't want anything with worn out bearings or scratches to lens. It needs to have smooth movement and be in "like new" condition. I would rather buy one made by Orion or Discovery, but will look at anything including homemade. I just want the scope and eyepieces ... not a lot of extras. Please let me know what you have, condition, and your price. Thanks.
