Yamaha DTXpress/DTXplorer/DTXtreme

Hi. I have a DMPro which has finally crapped out on me and I'm 
looking for a new unit. Can anyone steer me in the right direction 
for what I need? I don't have a full e-kit. I mainly use it with my 
acoustics for effects and a select few songs. I also need a unit 
that uses a flash card so I can make my own sound banks. Anything of 
decent quality out there for this type of application that's fairly 
user friendly? This is the only module I've ever had so I do need 
some guidance. Any help would be greatly appreciated.

Chris
