got a 15 cubic ft chest freezer in october for $400 delivered. a frigidaire. has been great for making good use of sales on meat. got some good buys right after thanksgiving. have hardly noticed much change in my electric bill. had the setting at about half. has been around -11F . been filling the empty space up with salt water jugs. about 4 cups of salt to a gallon. more stable thermal mass inside seemed a good idea. have cranked it up recently because my wife needed it cooler to make icecream cakes. and its sitting at about -30F . have been very happy with the model i got. and has been real nice to have a nice ham, turkey, or steak i got a good deal on some months ago.
