I am currently looking at course dates from both Mile2 as well as Intense School. If anyone can point me at (or away from) feedback to help me make a decision, please let me know.
I can't speak for Mile2, but Intense School is great (at least for the CISSP and Cisco courses...hell, Clement Dupouis is one of their instructors).
The one thing I'd recommend with any of them is asking who the instructor is and for access to their former students' feedback. Most of the good instructors out there can be researched fairly easily.
And now that we're off topic....time to try out that practice CCE test
