I have not bought side-art for my DK yet so I am curious what others recommend as well. I personally have my eye on
Mike's versionHowever, the ones you are looking at on eBay look very washed out. The colors either look dull or too neon. Now that could just be the result of the camera used to take the photo but I'm not sure. I feel like side-art should cost a lot more than $35.
Also, be very careful of the exact dimensions. I've heard other uses get side-art from eBay that were off by inches!
Edit: fixed the link to go to the DK side-art set NOT the double DK set.
