Please note that these classes are not completely targeted at SharePoint end users, but if you're at all curious about how to get started building your own custom web parts or applications using SharePoint these are worth taking a look at. My experience with these courses in the past is that they are a good way to introduce you to some of the tools and concepts involved in SharePoint development. You shouldn't expect to be a fully proficient developer after completing the courses, but you'll have your feet wet and you can't beat the price.
One thing I've noticed with the SharePoint end user experience is that once people get comfortable in the environment, their thoughts often turn to how they can customize their sites and tune them to meet their specific needs. That often leads to some gnashing of teeth when they come up against limitations of the platform out of the box. The great thing about the latest versions of SharePoint is that its much easier to develop against, but the learning curve is still pretty steep.
If you're an experienced SharePoint developer, I highly doubt there's going to be any great revelations for you in this training. However, if you're a new or novice developer, definitely check them out.
