UPDATE
just had the pulled pork 9 hours on the BBQ, nom nom enough for pack lunches for awhile, Other kettle BBQs are probably as good to be honest just dont get hung up on the gadgets all you need is a digital thermometer and some basic tools.
this site is V good tbh
http://www.amazingribs.com/index.html
the weber book is also good lots of recipies and explains the techniques
or get down to Grillfest music beer and BBQ what more does a man need.
dont get the small one as for indirect cooking it will reduce what you can cook, if you want to grill just get some fire bricks to push the coals together or if you want to sear steak raise the lower grate up on bricks so the heat is super intense.
^^^ as above it isnt the paint as it is enameled but it is the carbon for the smoke, the experts say to never close the top vents down when cooking.
