I think it depends on which rooms you're looking to furnish... for kids room, where the stuff is going to get at least a little beat up anyway, I love IKEA -- not too expensive, very versatile, and not too bad in the style department! And some of their solid-wood stuff is very nice, with clean lines and a classic look.
I live near Boston, and up here we have Boston Interiors, which has a lot of Crate and Barrel-esque stuff at a lower price.
Right now, our family room is sporting the "just got hit by a tornado" style of interior design. So I might not be best person to listen to for advice!
