PCMICROSTORE Brand Apple iPod Touch MP3 Video 8gb 16gb Premium Silicone Skin Case Cover with Touch Screen Protector Shield - 4 Color Options (1st Generation ONLY)
Good overall, the material makes dust stick to it though.  Also, other cases that I looked at customers had complained that the headphone jacks, attanae, and USB port plug were blocked but I had no problem with these.  The skin was thinner around those edges though, and I could not fit my iPod into my iHome stereo with the skin on it.
