Thanks everyone. All good advice and input!
I'm shifting gears a little bit and looking seriously at the sub-$500 market now, as well as used Webers on Craigslist. Cooks Illustrated rated the entry-level Weber Spirit II E-310 highly, and the price-point just dropped to $450, so I'm considering that one. There are a few on CL for $250-300. I found a great deal on a very clean high-end Weber Summit 4-burner in Denver for about $800, and if it's still for sale next week, I just might make a little road-trip and buy it. There's a Lumberjack pellet reseller up there too, so I could pick up my 2019 pellet supply...
Doing the taxes now, so depending on the size of the check I have to write to Uncle Sam, the gasser project may be put on hold!
