Have you considered whether it makes sense to get yours repaired? Before you buy a used one, which could go south at any time, give Loren a call at www.systemsc.com.

He might be able to (a) repair yours, or (b) sell you an overhauled unit at a reasonable price with a warranty. It's worth the call....
