GEN2 IRiver Clix 2GB 4GB 8GB (U20) Silicon Skin MP3 Case Cover with AdJustable Sports Armband - (Not Compatible with 1st Generation Clix) - 3 Color Choices
I was happy with the silicon case and the price, however the armband won't even fit around my forearm, it's so small.  Luckily, the case works with a different armband I had, so am content for now.
