Amazon will generally have good products at reasonable prices. I bought several cases for my HP Touchpad off there and was happy with the purchases. If you're willing to take a hit/gamble on quality then there's always eBay which will have the cheapest prices anywhere but you'll probably wind up waiting 2 1/2 months for it to be delivered from China. I would suggest you google search iPad 2 cases but you'll probably get over 12 billion results back. You can order form places like SW-Box, dealExtreme, monoprice for stuff too.
