Baby shower host gifts

Alexia
What's a good gift to get your parents for paying for your baby shower?  You would think the reward would be bringing their first grandchild into this world, but I would like to do more than that.   Lol. My sister just told me my parents have contributed almost $4000 towards the shower, which I feel is entirely too much.  It's kind of stressing me out actually.  I wish she would have never told me.  There better be a performance by Beyoncé or somebody cause....anyway, what would be a good gift to show our appreciation.  I want it to be nice.  Not the typical gift basket with wine, chocolate, etc in it, but something nice.  
I also want to get the hostesses something as well.  One of them will be my son's God mother, so I already know what I'm getting her, but the others include my sister, and my sorority sister. 
Thoughts and ideas?????
