I've used the Cheese Wizard's recipes many times and I'm yet to be disappointed. They are very easy to follow and do produce some good results. I use his Gouda recipe exclusively and have never yet had a failure.
The only point I disagree with him on is the amount of time to stir after adding the rennet. I never stir over 1 minute after this addition.
Give it a try. I'm sure you won't be disappointed.
