Welll, I can't really comment, since obviously I'm biased
Several people have taken the time to write to me directly to tell me how much they liked my work though, but that loses it's impact when I'm the one passing it on of course!
Anyway, there are a couple of free sample videos available on the InformIT site, so you can get an idea from them. If you follow the link in my "signature" block, you will get there, and be offered a significant discount too.
Another possibility is if you have a Safari (as in O'Reilly et al.'s Safari Books Online) subscription, you can watch the course there. The basic course material, but not the quizzes, are part of Safari.
I believe you can take a look at the reviews on those sites too without being logged in or having made a purchase.
Hope this helps a little.
Cheers,
Simon
