The Thetford stuff is generally good. It's used by a lot of campers in the US, when you want to set up for extended usage. Most of it is a bit on the bulky side for hikers, but fine if you've got a way to carry it.

I don't have a link at hand, but the "Mountaineering Clubs" commonly have links to sites with minimalist accessories - easy to carry, functional, and with the "products" neatly packaged to portage out. Climbers usually are pretty conscientious about the "leave no trace" philosophy, but don't - for obvious reasons - want to carry anything very bulky or heavy.
