Here's a tip ( that you may have already heard...! ): from what I can tell by looking at images online, the A1151 / A1212 / A1229 / A1261 use the same case, and a skin that fits one, may well fit all.
I just bought a very nice A1212, and looked on Ebay for a skin. Couldn't find one. A little later, while looking online at an IFIXIT description of how to remove the motherboard @ renewing the CPU paste, it seemed that the 4, 17" Apples were all alike, externally.
I went back to Ebay, looked for a skin for the A1151, and...there it was!
I bought mine from "LIDSTYLES", and the fit was just fine, and it went on very easily. I used quite a lot of glass cleaner ( with ammonia ), used the enclosed squeegee to gently smooth it on and push out the excess fluid, and that was that, with change back from $20 USD.
