Yamaha DTXpress/DTXplorer/DTXtreme

hey guys,

as some of u know i'm currently in the process of upgrading my setup. 
i've pretty much decided on the hart dynamics studio master 6.4 for 
the kit but am having alittle difficulty on choosing the 2nd brain

i already have a dtxpress I brain and am very happy with it and 
wouldn't really mind linkin 2 through a mixer, but i've also read 
alot about the Alesis DMpro and am not entirely sure what to make of 
it. many reviews have been very positive but all of them are alittle 
dated, and i'm thinkin perhaps the dmpro is kinda out of date. i 
really would like to add a different module to my setup as i'd love a 
wider variety of sounds and functions. however i've never used (or 
even seen) a dmpro and have no idea how it compares to the dtxpress.

i was wondering if anybody in the group has ever used a dmpro before 
(assuming that u all have dtxpress') how does it compare to the 
dtxpress brain? do u still think that its a good buy or are the 
samples old and out of date?

also if i decide against the dmpro, i'll probably go for a dtxpress 
II module. how does it compare to the dtxpress I module? are there 
any differences at all or is it essentially the same brain painted 
red?

cheers guys
pete
