Hi, I have done his spreadbetting course. It is okay if you are a complete beginner. Most of the modules will give you information on spreadbetting which is freely available on the internet. The core of his theory involves two finding trends using three MA crossovers - nothing new there - and then he has a 'bounce' entry strategy based on the RSI and MACD.
When I did the course in mid-2005, he dedicated very little of the course to risk management in any meaningful context and barely mentioned correct placement of stoplosses, let alone the most fundamental aspect of trading - like position sizing!
Stu seemed a genuine bloke. He was very slow to return modules on occasion but he is not a scam artist. His website lacked professionalism but he is not a cheat, like some out there.
However, when all is said and done, I do not consider what I learnt from him as more than very basic knowledge which may assist in my own trading strategy.
