I haven't heard great things about them.
If you could fit temperature control in the base it might be nice.
And you could use the Brewferm belgian kits as they're small ad good quality : http://www.homebrewwest.ie/brewferm-belgian-beer-kits-89-c.asp (http://www.homebrewwest.ie/brewferm-belgian-beer-kits-89-c.asp)
but you're still serving off the trub... and not even 10 liters at a time.
