Jim; My PERSONAL experience with USB 1 drives was BAD. I tend to stick with FW 400/80, as, depending on Mac Model and drive size, they can be buss powered and you can carry them in your shirt pocket. I've no direct experience with eSata drives, though my understanding is as yours, that external power is needed. I've friends and customers that have used USB 1/2 boot-able drives good success, I've only had trouble with full and pocket sized USB drives [this does NOT include Flash Drives - LOVE them].
