Depends on if you want to be right next to it all the time, or if you have a lot of time to learn how to get charcoal & wood pieces to the right temp, and hold it there, and all that tricky stuff. There are guys here who can make those kind of things do everything except go get your morning paper for you. Those guys amaze me!
I however like to go out, plug my MES 40 in, push my digital buttons to 230˚, put the meat in, close the door, and let the smoker do the rest. Throw in an A-MAZE-N-SMOKER, and I'm good to go.
MES 40 is electric, with a glass door remote control, wheels, built in meat probe & smoker heat sensor.
It costs about $300 for the one that is black on the outside & SS inside, or $350 to $400 for the one that is All Stainless (inside & out).
I would definitely recommend the MES 40, unless you like to rough it, like so many of the great smoking people on this forum.
