Thing is there's no need to go fancy either. I've been using a Big Chief electric smoker since the 80's, I'm on my third one now, but have one older one that still works and the original one needs an element, pot and tray. Sure it's fixed temp at 160° but it's all I need for most of the things I smoke and for larger chunks of meat I just finish the cooking process in the oven where I have perfect control. Brian is using the same thing and technique in his condo. They're real handy to use too, mine is on the back porch so I just pick it up and carry it into the kitchen where I load the racks, close the door and carry it back out to the porch plug it in and load the pan. No propane, no moving parts, no controls needed, all in a compact size that holds a fair amount with 5 racks.
Quick story. A while back I ran out of smoked paprika, I started doing my own a few years back and it's all I use now for the most part. So a week back I remembered to stop at a small natural products store in CP where I get my bulk spices and picked up a half pound of Hungarian for just over $5. I always want to try and fill the smoker as much as I can when it's going. With that in mind I had a half price frozen sourdough loaf that I thawed out, chunked and dried. Just so happens I had recently picked up a generic full pepperoni chub at a price I couldn't refuse. I've had real good results enhancing cured sausages in the smoker already too so that worked as my last rack. So then it's planned for the weekend and best hydro rates too. Smoker was plugged in for four hours yesterday with five smoke sessions. The result for $10 was three racks of golden sourdough pieces for bread crumbs, two glass pie pans of the best real smoked paprika you can get, it was actually quite sticky on the outer edges of the glass after I let it cool, and a darker skinned great smelling sausage that I vacuum sealed and froze half.
Cheers
