We have ordered our better stuff from 4Living. It is on 17th Ave SW and 14th St.
They have excellent quality furniture. The price vs. quality is good, although it is more than Ikea but less than BoConcept. A couch would run you about $2500ish-$4000ish depending on what you want. It is excellent quality and very current styling.
My opinion is if your going to go cheap, go to Ikea. If you are going to spend more, make sure it is good stuff, but not over the top expensive. Home Evolution, 4Living, even some of Crate and Barrel (on sale) is where I think value is.
However, when I win the lottery then I will be heading here:
