Any help or advise would be massively appreciated!
I'm no expert on semi-commercial cooking. There's a member here called Old Sarge who bought a dinged Cookshack Amerique SM066 for a bargain price and loves it. He'd be the guy to talk CS with. I can't afford one.
There was a guy also from the UK who posted a question about a Beelonia back in April. Here's the link: http://www.smokingmeatforums.com/t/185237/cold-smoking-with-my-beelonia-f5-having-small-issues
As far as I know those smokers aren't sold in the U.S. Good luck.
Just attended my first pro/am BBQ competition--to eat not to compete. Saw plenty of offset stick burners, Weber Smoky Mountains and Weber charcoal grills and a few...Cookshacks. Those were the pro big boy smokers not the home versions. I would say the Cookshack--if you can buy a 240v smoker--is a great choice.
