Best Training in Linux Administration?

Love to Learn Linux asks: "My company is making the move to Linux. I've been a Windows admin the last 5 years and have been asked to learn Linux. I've got some O'Reilly books but I need some hands on experience. My company will pay for any Linux training I choose. I'd prefer an online course to one of those 4 day classroom courses since I'd like to take my time and really learn it. So far, I've been recommended the Red Hat eLearning course and the O'Reilly Learning Lab. Would you recommend either of these over the other, or are there some better choices?"
