Where can one buy a "quality" sofa and still save a buck? (Craigslist is surprisingly weak in my area!)

In the market for a new sofa. Was hoping to spend less than $500 and have been scavenging Craigslist daily but just can't find any sectionals (we're looking for L-shapes) that are any good, even in the $1000+ range!

I am still looking around but can anyone offer any insight as to where to get passable large piece furniture without wrecking a budget? Cheers

Edit: guys thanks for all of these suggestions - will definetly check out these places :)
