It's too bad that Pottery Barn Kids doesn't ship outside of the United States. I did a quick ebay search for pottery barn kids mobiles, and came up with several promising results.

I also found a few other sellers of similar mobiles that will most likely ship internationally.

I used to live in Switzerland and did a lot of online shopping. Pottery Barn will ship internationally. If you look at the bottom of their Shipping Info page, it says to call the Customer Service number for more info. Although the shipping may be more than it is worth.

You can buy these for $15.00 in Kmart
