What is a good source for area rugs?

I'm looking for something in a neutral (tan/gray) with a subtle tone-on-tone design. Perhaps a Greek key or a "trellis" or "x" pattern. When I spot one in a magazine that catches my eye, and then check the sources in the back of the book, they are always thousands of dollars. I'm looking for something more in the $100s. I need approximately a 8' by 10 or 11'.
