Yamaha DTXpress/DTXplorer/DTXtreme

I've had my DTXpress for about a year now and love it.  The only problem
i've every really had with it is the cruddy kick pedal.  It seemed that
it just died on me, so i sent it back to Yamaha two months ago, and
still haven't recieved word back on it.  So now I have no kick pedal,
and I'm using the HH pedal as the kick on the left side for now...  The
question I have, is what pedal would you guys recomend for someone on a
budget that needs a replacement kick trigger?
