They get my vote as well. I love their tutorials, very affordable indeed and they are helpful. I haven't tried others, they're just to expensive for my taste. Perhaps one day I may buy one of quadspinners tutorials, but I do find them overpriced for what you seem to get. Didn't find their free trial ones better then the ones I got at GeekAtPlay.

Due to the childish TOS changes, I'm not allowed to link to my other products outside of Rendo anymore :(

Food for thought.....
