If you use an electric smoker like that you'll want a smoke generator like the A-Maze-N or Amazen tube smoker to go with it. Those things don't produce good smoke on their own.
True cold smoke is under 100 degrees and there are plenty of options for that like the Amazens, Smoke Daddy's
I'm going to make a pellet UDS one of these days and it'll produce temps from about 100* to about 450*. Primarily i want to do the same things as you in it...sausages, jerkey etc..
