Refurbished Units Available

Refurbished units are now available at a discount price! These units may have been briefly owned by others and returned, or may have been returned to us by Amazon for whatever reason. They have been thoroughly retested, and our three-year warranty still applies to all units sold.  A tab or two may be missing from the bottom of the center section, but the unit will function well. Tabs thus missing will not be cause for replacement of the center section. Refurbished units may or may not have an in-line on/off switch, depending on when they were manufactured. Buyers of refurbished units do not have a choice in the on/off switch.
