My wife is a big fan of his stuff. She's been to the UK, France, Italy, Greece, Turkey, Egypt, Thailand, Dominican Republic, Haiti, all over Mexico, and a few places and has often used his guides.

We rented a few Rick Steves videos regarding Paris and the south of France and I just found them more geared for the tour group crowd ($$$$$ as opposed to $$). His language guides are great, but I think I'll have to stick with my lonely planet for travel and accommodation.
