Yamaha DTXpress/DTXplorer/DTXtreme

hello everyone,

i'm contemplating buying as many as 6 new pintech tc 10's in order to 
emulate a much fuller cymbal set up. however i've never seen or used 
these cymbals before and haven't heard much about them at all. if 
anybody in the group has any experience with them, please let me 
know, even if its something short it would be much appreciated!

thanks
pete
