JC Penney has several options online and I'm pretty sure they have a few in the store you can try out before you order one. I've also seen on at Ileigh's Dreams (I think that's what it's called) in Memphis Place Mall. Dutalier is a good brand, but they are pretty expensive. You can find them at a bunch of places online.
Good luck and congrats! My daughter was due June 3 this year and I had her on May 16. I was like you and got started on her nursery right away :).
