Yamaha DTXpress/DTXplorer/DTXtreme

hey everyone haven't posted for quite a while,

as some of u know i got the an old dtxpress, i'm currently lookin into
buyin a new kick pedal to replace the KPwhatever it is that i got with
the kit all those light years ago. lookin into gettin one of those
pedals which hits face down, rather than straight ahead like a
standard pedal (like inverse, i think its called) 

anyways just hopin that perhaps somebody may have a hint or 2 to give
me before i buy. perhaps on whats a good pedal 2 look at, i'm lookin
at the cheaper scale of things - primarily 4 practicin. oh and i'm
based in london 2 if anybody knows of a good shop in the UK. 

if anybody has any ideas whatesoever plz let us know, gonna buy this
week hopefully - if i find somwthin i like! 

cheers,
