I for one have happily forked over my money.
The quality of information is exceptional and if you want to undertake formal study there are no better resources available than the GCB (General Certificate in Brewing), CD based study material.
The short brewing course at Ballarat costs around $2,000; the upcoming NNL week long course at Potters is around $1,300.
IBD training is recognised world wide and is I think exceptional value for money.
I would haply recommend any of the above to anyone who wants to learn more about brewing.
Whichever choice you make it is going to cost - but quality always does.
