Hi Tom: I just installed a portable I bought at Costco for $160. Stainless steel, you can put bottles water in it, showed 3.2 amps on my Kill-a-Watt, and makes 32 lbs per day. Each cycle takes about 12-13 minutes. Thus far we think it is great! Mike Mann M/V "CaptRose" 43' Harkers Island Trawler Hampstead, NC
