you can get them from home depot as well as other places.

Really? What does 'way over the top' mean for efficiency? How many $ is 'a lot extra'?
Electric water heaters all have efficiencies that are very close to each other, just due to the nature of how they work (resistive heating elements immersed in water are near 100% efficient). The amount of insulation will make a small difference. Until you go to a heat-pump model.
I'd be very interested to see your calculations that the efficiency will save you money, or even much energy.
The OP's main water heater is propane, which will cost less than electricity in his area.
