I have the LP Richie "Gajate" Garcia gajate bracket.  It comes with a plastic jam block which is very loud and the sucker is easy to swap out with a cowbell.  I have no complaints- have used it quite a bit and it has held up well for being made "across the pond".

I'm sure the pearl is fine.  You are going to need a nice auxillary pedal though.  I have an axis X pedal, but I'm swapping it out with a sonor giant steps twin effects pedal (should be in this week at the drum shop) and I'm moving my axis pedal over to the right of my main kick with another gajate bracket to practice *gulp* three pedal technique.

My genius never stops...and neither does my credit.
