Closic's Baby and Teen Furniture in Wilmington, DE. It's worth the drive. The sets are set up very nicely, so you can get an idea of how you could decorate your room. Also, the have competitive pricing. I got mine there and it's beautiful. It was an overall good experience.
We got ours at Baby Supermart in Broomall. It was in the Baby Bargains book and definitely a great place. Tons of options, good prices and nice people.
