You answered your own question. Pellet grills remove the "right effort," and pellet grills are proliferating. I'm not judging it at all; I bought an ATC so I can sleep on overnight cooks. A buddy of mine and I took a KCBS judging class 15 years ago to turn learn more about bbq and we both bought WSMs (though he also got a stick burner). Three years ago he bought a pellet pooper and he hasn't used his WSM or stick burner since.Jon; to add to your comment above; I have Read a bunch of comments on this Forum relating to new and well-conditioned used WSM's being bought On-the-very-Cheap and my question is Why?
I bought my WSM 18" "Classic" new in the year 2008 and at that time it fit all my BBQ needs and still will do a great cook if I put-in the right effort.
