I would encourage you to take a look at the BCS-460 and BCS-462 fromwww.embeddedcontrolconcepts.com
... Using a web browser and the BCS you can control the temps of your vessels and RIMS/HERMS equipment. I've been using it for 3 years and it is setup for RIMS... and it can also be used to control your lager chamber or freezer full of kegs.
When I started brewing 6 years ago I was using 5 & 10 gal. Orange coolers, then decided to move up to Blichmann 20 gal kettles for my Mashtun, HLT and Boil Kettles. If I would have waited a little longer I would probably have purchased kettles from Brewers Hardware instead because I use alot of Tri-Clover fittings in my setup ... http://www.homebrewersassociation.org/pages/community/pimp-my-system/show?title=pimp-my-system-ale-force-1
I have a friend who purchased kettles from Stout Tanks and is happy with his purchase.
