I normally gravitate toward simple geometric rugs, but lately I've been really drawn to more traditional, intricate styles. I am particularly crazy about the Sarafina rug from Ballard. Traditional and interesting, very old world. The steely blue color is perfect.
The 8' x 11' Sarafina rug (above) costs $1,000--which I know is expensive, but isn't a terrible price for a large, well-made rug. But this Costco rug is kind of a steal-- $480 for an 8' x 11'! I love the colors and it has especially great balance between warm/cool/neutral tones.
