They're made by AIR CRAFT and allerc is the best place to buy them. The customer service at Air Craft is top notch. I bought two EOS 5i's from allerc and the screen was a little dim on one of them. I sent Air Craft an email about the problem, to remedy the situation they sent me a brand new one and told me to keep the "old" one for parts if I ever need them, even though it works perfect besides the characters not being as dark as on the others. They also sent me a Hyperion t-shirt with a big Hyperion logo embroidered on the back and a bunch of huge Hyperion stickers as well. Best customer service I have encountered yet.
