If you are looking for industrial chic, look no further. McMaster-Carr is a resource that keeps getting mentioned in house tours, particularly out West. For example, check out the fittings in the bedroom at Todd and Nicole's Project Precita (see below).

Not a particularly easy site to navigate or get a feel for, nevertheless, behind each link lies dozens and dozens of industrial products from lighting to desks to doors to plumbing... on and on.. all of which are useful, unique and have good prices. If you are doing a DIY on your place and want to go a more industrial route, this is mecca.
