Hi Pete,
As you know I have this book and rate it highly, the recipes are very good, its a good read and has loads of recipes. The only downside is that his base sauce doesnt produce a high quantity so I use his recipes with your base and they are superb.
The easy way to download the whole book is to install a tool like flashget and then when on the index page right click and select 'Download all by flashget'
Dave's CTM recipe is the best I have found, I have also tried his recipes for madras, balti, bhuna and jalfrezi and all are great, well worth the 8 quid although I think his forum will suffer due to it being members only but it is good that you can speak to Dave direct on it.
cheers
