Ive only seen one Colman Sterling cooler, 3 yrs ago as a demo unit. Having been discontinued, it makes you wonder why.... I installed a Swing Sawafuji compressor and converted my ice box into a refer. Low power consumption and a bag of ice will last many days for use in my favorite beverages. The swing compressors have been made for yrs and still are on the market....
