David, First off you'll want to look at http://www.energystar.gov/index.cfm?fuseaction=find_a_product.And shop for lowest kwh/year. I have an Avanti 651 with a SS front. It's 6.3 cu. ft. Manual defrost of freezer rated at 254KWH/yr. The Summit model you mention may a good choice also, check it's energy star rating, I think it is 285 KWH/yr. Also, try to get one that has the condenser coils on the back, if it does you can add insulation to reduce power use. I added 1" of R7 foam round the sides,bottom and back of mine and 1.5" on the top. I also relocated the compressor about 2" further to the rear. These changes reduced my measured power usage to 19 W average over 24 hours or in the energy star units 166kwh/yr, but my initial measurement was 223kwh/yr. BTW The peak wattage with the compressor running is 150 watts or about 1.25 amps, far less than the 4.3 mentioned above. RegardsJerry 4107 1120
