It sounds like an important thing to ask yourself might be how much do you enjoy the process, compared to just the results? A lot of posts suggest "buy once cry once," and no one is suggesting a traditional side smoker or anything that uses actual coals and/or wood. So I'm going to assume that the buy once, cry once suggestions are mostly in reference to the ease of the actual cook and being involved as little as possible. I'm pretty much in that camp myself because the thought of trying to maintain a steady temp from a fire I built myself seems pretty intimidating, let alone for several hours.
