$25 per month and you can watch all the tutorials you want on photoshop CS5, Lightroom 3, and any other program that has anything to do with photography.
It's a great site.
Personally I like the tutorials that Chris Orwig puts together there. He has beginner and advanced tutorials for Photoshop. Both are about 14 hours long and he goes through the whole program and all the tools.
His Lightroom 3 tutorial is about 12 hours long and covers absolutely everything you would want to know about the program.
The best thing? You can cancel the membership after a month if you finish the tutorials and subscribe at a later time to learn about something else or refresh a program you haven't used in a while. $25 for this service is a steal and well worth it. I recommend you give it a try before you spend $650 for a 6 hour course.
+1 for Lynda, I've learned so much from that site it's not even funny. It's broken down really well, and you could use it for 2 years for $650. It's all very visual and all of the tutorials are high quality. They have courses on everything from actual photography to pretty much every single CS5 app, as well as highly complex 3D applications and whatnot.
Try out the Lightroom course on Lynda, and if you still feel the need to take the class after that, go for it. But to hell with $650 for ONE day...regardless of how good the course is, you can only take in so much in that amount of time.
Cliffnotes: $650/1 day course < $25/class for a month + $625 of new gear
Kudos to you either way for taking the time and effort to learn proper techniques (something so many ignore nowadays).
