Looks like a good deal. I currently have a Takagi tankless which has been wonderful. I believe the AO Smith line is made by Takagi.

My Tanked water heater is 15 years old, working fine...but has never had any maintenance done.
Downloaded the PDF manual before I got it, and it looks easy enough to install myself.
Google says tanked water heaters last 8 - 12 years and tankless last up to 20 years.

This is Wednesday (Yesterday (Tuesday) I had a great motorcycle ride, got rained on and everything_}
So this morning my moisture detector under my water heater tank went off, notifying the app on my phone.
My water heater sprung a pretty significant leak.
(Yes, moisture detectors really work! I recommend them highly. Also detected a minor leak in the faucet feeding the washing machine.)
So, I spent my day getting estimates for installation of this water heater.
(I did want to do it myself, but my wife wants it done and done right, and done fast...go figure.)
So, $2,400 some odd for installation and $600 some odd for this water heater (Thanks again OP) for a total of about $3,100.
I swear I didn't touch the existing water heater!
