Ok, I see -so you want a fairly large unit. I was going to harass you for going electric and suggest that you just get the Webber Bullet (what I have) but you said the magic words "cold smoke". I wouldn't mind an electric smoker so I could cold smoke fish and sausage (not that I make sausage much these days -so much work !) but frankly, I'm almost scared that if I got one I'd get lazy and not use my charcoal unit anymore !

Any interest in rolling your own controller ? I used to sell microcontrollers for a living and if you like electronics, you can have a lot of fun making exactly what you want, yourself !

I figure it's just a matter of time before I design autonomous systems to monitor my tanks' variables, ATO -maybe some dosing in the future.....
