From what I saw in the demo it is very good, but I want to wait for buy it until an update is available.

StrataTrain is a great resource....especially for beginners.  As for our supplemental videos it contains more advanced videos that extends the StrataTrain Videos.  We plan to add many more videos as well over the next 12 months which will include Role Based Security, more How-To videos, etc.

I highly recommend StrataTrain!
