Yamaha DTXpress/DTXplorer/DTXtreme

Hey, I'm new to the group and I have an original dtx1 set, with single 
zone pads and cymbals.  I'd like to get a dual zone snare pad for this 
set.  Any advice on a good dealer for parts like this, or anyone have 
one for sale used.  

Also, when buying pads for this set, do they come with the tube clamps 
to put them on the set?  I'd like to move my existing snare over to 
use as a ride.

Thanks!
