LOL, I just posted about this below.
This one is really pretty...not too large at all and really makes a girls room...one of my good friends has it in her daughter's nursery and it just makes the room.
Or this one if you wanted something a bit bigger...
I have seen a few in store that are inexpensive and very cute as well.
If you click on my profile pic and go to my bio...my dd nursery pictures are there with the chandelier. We got it from ikea $40.
Here is my chandelier, from Pottery Barn kids. This photo doesn't show it that well, but you can go to my bio or blog & see it a little bit bigger!

We got ours at Lowes!
