Yamaha DTXpress/DTXplorer/DTXtreme

Hey all,

I've been lurking on this list for a few weeks, but this is my first time
posting. I'm a new drummer and I joined the list shortly after getting my
DTXPress set. I've really enjoyed the kit and I purchased a TP80 and PCY80
pad to have a dual-zone snare and cymbal. Now I have the original TP60 and
PCY60 pad that I'd like to mount on the kit as well, but I've only found
hardware from two places online and they were -really- expensive. Where
would be the best place to get something like another one of the standard
cymbal arms and another 'T' connector and 'spike' for the tom?

Thanks,

James
