Yamaha DTXpress/DTXplorer/DTXtreme

hey folks,

i'm new here and thinking of buying the DTXpress since i live in a 
apartment. Any thoughts on this set for jazz music as far as 
sensitivity and nuances...?
By the way, i also appreciate all the input on this board its helping 
to make a decision. ALSO, i live in Germany and can only find the 
DTXpress not DTXpress II and the best price i'm finding is $800.00 
USED, this seems steep for a first generation used set, what do you 
think?

thanks!
