feedback with regards to the isdx training offered by ptc

I would like to get some feedback for those who've taken the isdx training course on whether or not it was worth it. My company primarily uses the software coach from cadtrain to train people in-house. I would like to know if there were things that you learned from the course that you never would've picked up from self-study software modules like coach.

I have taken a surfacing course through Rand and have found that they basically take you through a book step by step.

They have no real world experience so if you have the time it may be worth using coach.

Iam not sure if PTC is the same though.
