Trading Spaces sucks. It was fun for the first season, but it's just so tiresome.
A better show, the secret addiction in my family, is designer's challenge. Real people work with real designers and spend real money to get a problem room redone. You get to see three different designer proposals, with explanations of why they are choosing different options. Another great choice is Design on a Dime -- 1500 budget, real designers, they show the shopping and color choices.
Trading Spaces is all drama, no design.
