Yamaha DTXpress/DTXplorer/DTXtreme

Hi all,

Just Bought a second hand DT Xpress and am blown away by what I've 
discovered so far. Does anyone have any good tips for sounds, pads 
headphones or Amps ?
I have heard that there is a book by a Pro Drummer called Russ Miller 
and would be grateful if anyone could let me know how to get hold of 
a copy...is the book just for DTX or is at mainly aimed at begginers 
to Drumming.

I'd be grateful for any help you could give.

Cheers, Steve.

ps. I am a 35 year old "has Been" from Cambridgeshire , England. 
Is this  JUst for USA users or for everyone....no offence meant.
