...Build a great camera like the EOS1, the 5D, or 20D that I own. Sell it at a competitive price. Then, sell accessories for it and sell them at a 1000% markup. Be sure to patent the product so that no third party can produce a less expensive version. Want an example? Try this Remote Switch for instance.Here's how it works. You connect it to the camera. Press the button half-way, you get focus, exposure metering, etc. Press the rest of the way, you have a photo. Pretty simple stuff.Functional? Yes. Practical? definitely- a must have in fact for tripod users. Worth $50? No way. This product gets 2 stars from me because I'm insulted that I had to pay so much for it given its value.Want more examples? Try a Canon lens hood for $50 or a rechargeable battery for the same amount. (Hint: Look around, you'll find non-Canon batteries for 1/3 the price with higher capacity -- they didn't get us on that one!)
