Any suggestions on the best places to Google...
I might be missing something here, but the whole purpose of Google is to have IT do the searching for you.
When I was shopping for a water heater last year, I went to my search engine and typed in "Seaward 6 gallon water heater" and got about ten hits from companies selling them. I looked at each and found the lowest price and bought from them.
I'm pretty sure that's how it works.
There's also Craigslist and eBay.
Good luck.
