I saw their Stockbox program in action a year or so ago when a friend bought it to try it for a month....ultimately he gave it up to learn his own method but he said it helped keep him honest on his entries and exits.
In my case last Dec I was part of a joint special deal with DTI and TTM for a $40 webinar one Saturday - I found it quite useful and gave me a ton of great information on technical trading to read and learn from. IMHO $40 and 5 hours very well spent.
But I've not taken any of their courses or such, sorry. That's about all I can say about 'em.
