I've been on EPLAN P8 for 3 years, it is a very powerfull program and quite easy to use when you catch it, at first is a bit complicated, things aren't as obvious as they should be so the learning curve is a bit slow at first but you will like it when you are a bit more experienced with it. I really like the way things can be drawn and the use of macros, also his internal database for components.
I found many tutorial in the net, just use google, is very easy to found these. Even there is an official application from the manufacturer, something like a compendium or a tutorial inside a program, about 1CD size. I found it also in google.
