My advice to those out there moaning about the prices of Eyetech's AmigaOne bundles is buy the board and cpu from Eyetech and buy everything else from wherever you can get it, the cheapest as along as you know what bits are supported by AmigaOS 4.0.
Building up a system isn't like rocket science.
Myself, I wouldn't buy one of their bundles and the only reason I can think of buying one of them, is if you're really worried that you don't know what you're doing or for piece of mind.
