Help me find a good iPod Touch 4th gen case?

So I've been looking around for a new case or two on the internet for my iPod Touch 4th gen.. When I first ordered it on Amazon, I also ordered two cases with it. One was rubber, and it works okay but has problems staying on when I touch the screen in various ways. The other one was a hard shell, which worked great until I realized I couldn't exactly take it off whenever I wanted. The things on the sides that held it on (it was two parts, the case on the back and the little outline on the front holding it on) started to break eventually though, and I was able to get it off but obviously it's not going back on. I want to order a good and reliable case or two. Hard shell or rubber, whichever works good. I'll be ordering off the internet, and I would prefer that I could find it on Amazon. If Ebay, it has to be a buy it now, I don't want to have to worry about bidding. Anywhere else, it needs to be a reliable site. Thanks in advance for the help.
