I've still had some flareups with the 13 flavorizers.
Looks great-I'd never seen a platinum red. Had a big ass platinum green for a while that I finally sold. The platinums had stainless steel flavorizers stock, I think, along with a funky plastic handle, at least in the older one I had (with big, non folding porcelain coated side table and a monster side burner).
Left right orientation is good for rotisserieing, but not great for indirect cooking or just doing like one or two burgers. Mostly I think they switched because they were the only ones doing it left to right and people wanted a grill that looks like what everybody else uses. The low end Weber gas grills are really crappy right now. My co-worker just bought one and is super excited about it. I didn't have the heart to tell her that she should have ponied up the extra couple hundred for the Genesis if she was buying new (and really should have hunted down one of these bad boys).
