A great electric smoker is anything by
Cookshack. I have their "
Smokette Elite" (SM025) and it's a beast. Built like a tank, and would probably survive a nuclear holocaust. But more importantly, is a "set and forget" electric smoker. Put 2-4 oz of a good, hefty wood chunk or two in to the smoke box..set your temp. Load up the food, and insert the (included) probe so that you constantly monitor food temp.
Could not be easier. I also own a Big Green Egg (albeit, a Mini, which wouldn't suffice for smoking) and a Kamado Joe (large) which many people would use for smoking. But the ease of use of the SM025 over the KJ is LIGHT YEARS better. (For example, I don't need to load a ton of lump into the KJ, setup separate temp controllers and fans, and most likely reload the lump at some point during a long cook). Plus, I don't have to worry about potentially setting my deck on fire when I kick on the Cookshack, as the smoke box is totally contained and there's NO WAY even the smallest spark is ever getting out of the cook box. KJ with all that natural lump, flame and sparks? No way I'd leave that thing unattended on my wood deck, especially overnight.
IMHO, you can't go wrong with anything by Cookshack. They make commercial, competition-level and "enthusiast" gear. It's not cheap, but it will last you a lifetime. Hell, my SM025 will almost certainly outlive me. Nuclear war or not..(you'll know what I'm talking about if you ever see one..they just don't build things like Cookshacks any longer..)
PS: I just re-read the SM025 page and it mentions using "year round". Oh, yeah. I live in MI and have smoked Pork Butt, Ribs and Brisket on days with 16'' of snow on my deck, and the thermometer reading sub zero. The SM025 has more insulation than my house. And it's built out of (many layers) of solid metal. The thing is a BEAST and totally indestructible. You could probably run it just fine in the middle of the worst winter day in central Siberia, and it'd do JUST. FINE. and turn out some great Q.
As far as ELECTRIC smokers, you can't beat a Cookshack IMHO. That said, there's a whole passionate, religious discussion around Electric vs. Lump vs Stick Burners vs. Pellet Burners, etc..good luck!
ETA - the SM025 has a
separately sold cart that it stacks on top of. Highly recommended, as the base unit would be low to the ground without this..they are also made entirely in the USA. I think they're welded (yeah, welded) together in Oklahoma, or somewhere similar where big, burly men rip large trees from the ground with their bare hands before wrestling down a buffalo or two for dinner.
