if Mr Jimmy Lee's too busy you could always find Mr Tony Zee or Mr Hensen Beng... excellent superheros.
if you are taught by Mr Beng, he will pass to you a book that has really a lot of stuff to check out. he teaches from that book, but teaches much more than the book shows.
i got Drummers' Bible, and 4-way coordination. still would recommend a teacher though. didn't make much headway until i got under Mr Beng, and everything just went ZOOM. besides, a book full of notes don't really motivate you to play until you see what they can do for you musically. till then they will just be really technical stuff that is really great to achieve, yet the journey would be dry and mundane.
then again, Mr Beng is not really one who teaches technique, but more of like being a versatile player. he don't really go into grip and all. that one, Mr Jimmy Lee the man...
