Yamaha DTXpress/DTXplorer/DTXtreme

I've been able to get one of these in my kit, and though I haven't 
had a lot of time with it, my first impressions are really 
positive.  It tracks well, seems to bring out the best in the Yamaha 
ride sounds (that's saying something), has a nice feel, and 
doesn't make a lot of noise. But at this point, what I like best 
about it is that if you choose the right combination of ride for the 
body and crash for the rim, you can get that kind of symbiotic 
ride/crash effect that an acoustic ride will give you when it swings 
just right.  I've never been able to get that with a Roland or 
Yamaha.  Also, the price is right.  I wonder how it stacks up 
against the Harts.
