The SM tutorials are nice, cause you see the actual process from start till end, but personally I have found the Digital tutors DVDs to be quite informative, for the beginner..
SM's DVD's are quite cheap, Digital tutors are midranged in price
Gnomon DVDs is more for the intermidiate - advanced (and also cost a bit more)
