I live in Lawrenceville and there is a big "Doll Houses" store just at the on ramp of Ronald Regan Blvd on Hwy 29. It's next door to the fire station. I think if you are in the market for a doll house, that would be a great place!
We got doodle a BIG one for Christmas last year, so 2 1/2. It was our big present for her, so it was expensive - cost $80 from costco. It's 3 stories and has a crankable elevator. She LOVES it. I don't know if this is whatyou're in the market for or not, but I can find the brand out if you want.
Re: Doll House
I love the "My First DollHouse" and Fisher Price "Little People" Dollhouse with the chunky plastic dolls.
