Just got my SP3 last week and wanted to get a protective case because I take it to work so often. I found a neoprene case on Amazon for 10$ and was really surprised at the quality. It has a zipper style opening and I can just slip my SP3 in and out. It has carrying handles too which are sort of nice. It's called an amCase and was only around 10$ with free shipping as well, so it was def worth the money. Comes in black, which I got, and I think they had other colors too.
