I had a gasser and wanted a smoker. I am not mechanically inclined enough to build my own. I made a lot of ash trays in shop classes.
I looked at all types of smokers to buy and finally settled on the 22.5 WSM. After a few mods on it to create a fire basket / grate stand, I can use it to cook anything from seared steaks to smoked briskets / butts / ribs.
Very happy with my purchase, but my gasser is getting a little lonely. Only fire her up to light my charcoal...
