Where Do You Go For Linux Training?

Spritzer writes "I work for a rather large corporation with multiple divisions around the world. Nearly all user computers in the company are Windows systems, and there is no plan to move to Linux in the future. However, a good many of our products are now designed to run on Linux systems for security and stability purposes. Obviously, the design/development teams are knowledgeable in the use of Linux operating systems. Unfortunately my field service teams are not, and their is no in-house training program. This has begun to affect our ability to provide efficient, quality service to customers when in the field. So, we need training and would prefer to stay away from online, self-paced courses and get our people some hands on training with an instructor. What training services have you used in the past to get people trained in the basics of using?"
