It looks seious -- I glanced at one on Classical Mechanics, and it's taught by a prof at MIT.

How bad can that be for the price?

Just to mention, I've been looking at the course on Astrobiology (from Stanford University). The production quality is lousy, but the content is great. I heartily recommend this one.

But wait -- there's MORE!!

Just spotted this today -- freebies from MIT!

Only the one course to start with, and it runs from March through June of this year.
