Looking at a Kenmore Power Miser 12 gas water heater (need 75 gallon) since
it has a 12 year warranty. But I have no experience with the Kenmoore brand,
just Rheem and Whirlpool. Any known issues?

What are some good quality gas 75 gallon water heaters with 10-12 year
warranties, say in the $500-$70 range (w/o installation)?
