Steven, I'm going to reffer you here: http://www.thehomebrewforum.co.uk/index.php
I can't find anyone current here in any of the pressure barrel threads who actually uses them. Most folks are making the same comments as everyone on this thread.which isn't helping you, like I said we don't see many of these in the states.
I suggest you ask your UK brethren, but when you start a thread there put "Pressure Barrel" in your title, it will help get you the right attention.
Like my snazzy new avatar? Get Sons of Zymurgy swag, here, and brew with the best.

I gotta tell ya, just between us girls, that Revvy is HOT. Very tall, gorgeous grey hair and a terrific smile. He's very good looking in person, with a charismatic personality... he drives like a ****ing maniac! - YooperBrew
