Yamaha DTXpress/DTXplorer/DTXtreme

I bought som older sysnsonics drum pads and the stands from som kid for a hundred bucks.
I like the size of the pads but I don't know about the responsivness? I looked inside 
and the piezo unit is taped to a round peice of wood inside that makes up the shape of the drum...hmmmmm?????
also the pads are made out of extreemly brittle plastic that cracks easy.

I wanted to buy a drum brain to go with these pads but I realized that it would cost the same to just buy the whole dtxpress 
kit with every thing brand new.
900 bucks is pretty cheap for the whole kit with every thing.(price of a cheap computer)
somtimes I just get frusterated and want to buy new equiptment and at that price it seems phesable.

although I read on here that a lot of people recomend just geting the brain or replacing most of the factory componants
with better more reliable ones.
I know about logiztix pads but that is just my point.... are yamaha factory pads that lame that one would definatly 
want to look for other pad options????

what should I do????

and it dosn't help that I live in a one horse town where my local music store has no e-drums to demo before I buy.
duuhh...what are e-drums?

thanks guys...
