Kenmore 50 gal. Tall Natural Gas Water Heater (33205) —
Was the best I could find. Don't really have a lot to add to the review. Only thing I was disappointed with is that for this money it should come with more insulation and the power vent is not made to have the intake run outside (so you have the warm air in your home being fed to the fire then dumped outside). Considering this is the 'supper efficient' model. I put it in a the house we just built so I can't comment on $$ savings.
