Yamaha DTXpress/DTXplorer/DTXtreme

I just bought my DTXpress a month ago.  This was my first set of e-
drum, even right out-of-the-box, I was very impressed by what it can 
do (for the amount of money I paid).

I have already upgraded Tom 1 & 2 to dual zone pads and added a 4th 
Tom to the set (Input 9 via a TRS splitter).  For my next upgrade, I 
want to plug the current Ride cymbal (PCY80) into Input 10 and use it 
as a 2nd Crash and buy a better Ride cymbal to take the Ride input.

I am having trouble finding the cymbal to the specs that I need.  
What I need is a Stereo cymbal trigger with bell/bow (I don't need 
edge).

Everything I've seen so far is bow/edge trigger.  As you know, Stereo 
triggers plugging into the Ride input must be 1 piezo/1 switch 
configuration.

Where can I find such animal?  Please help.
