IMO, I think they're perfect for someone who wants to grill/smoke but doesn't want to fool w/gas, charcoal, etc. or tend to a grill that much ... I'm actually trying to get my sister & BIL to buy into one ...
I don't own one ('cause I *DO* like to fool w/gas, charcoal, etc. LOL) but I've heard from friends of Camp Chef grills that they're awesome...
To me, the cons are price & electricity
