DD's crib bedding was PBK and it was awesome (I actually bought it lightly used on ebay, used it for about 2 years, and sold it again on ebay and made all of my money back. The stuff is amazing quality and holds the value extremely well.)
When I changed DD's bed to a Toddler bed I got bedding from Target. Not as amazing as PBK but it's holding up really well, too.
I'm about to convert her bedding to a Full and i'm really resisting the urge to buy PBK again (just because it's so expensive... The cost of just the duvet that I want is the same price that I paid for the entire nursery collection that I had w/all of the bedding, area rug, curtains, etc...) It will last a long time though, which I know is worth it...
