Yamaha DTXpress/DTXplorer/DTXtreme

Hi all
I want to buy an E-drum and I have some questions

1)Where I can find some dtxtreme IIs video demos and reviews?
2)What do you think about the dtxtreme IIS system?
3)Do you suggest me to buy the dtxpress III special or the Roland
TD-6s new kit and why?

I have seen all the material around the web about the dtxpress III
special and the roland TD-6s, and now i must give me an answer... what
do you suggest me? I must buy the kit until the end of the week! Thank
you!

Alex
