Best commercial tutorial?

I am finally undertaking the overwhelming task of jumping into Blender feet first. That said, I would like to take the most efficient course from A to B, and so learning these random tutorials bit by bit doesn’t make sense to me. Can anyone recommend the best commercial tutorial out there? I really like Blender Guru’s style the best, but he unfortunately has yet to provide a comprehensive tutorial. I am only interested in modelling hard surfaces, so I don’t need character animation. Can anyone guide me in the right direction before I plunk down 30-60 dollars and several hours of my time? Thanks! Jonathan
