Found this at Peddlers mall yesterday for $10. Other than the handle lock being worn out, It is in very good shape, including the bearings. It is a screamer,but not the worst i have had. It is light and small enough to vacuum the cat tree lol.

If it is loud, take it apart and clear out the fan and, if that does not work, get some non detergent electric motor oil and oil the bearings as best you can.
