Yamaha DTXpress/DTXplorer/DTXtreme

Hello all,

I'm a complete newbie (both to e-drums and to drums in general) who
bought a used first-generation DTXpress off eBay in the spirit of fun
and experimentation. Everything seems to work great, except for the kick
tower, which is completely dead. The cause of death may have been the 
"tender" ministrations of UPS. In any case, I'm now in the market for a
new kick trigger (preferably cheap), and was looking at the KP65. I have
a few questions, to wit:

1) Will the KP65 work with the old DTXpress module?
2) How is the noise level compared to the KP60, which seems quite
loud and clangy?
3) Are there any other good options in a similar price range? (Seems
unlikely.)
4) What does the KP65 actually look like? Is it a large circular rubber
pad atop two "buttresses", or does it look kind of like the KP60? I've
seen pictures of both called the KP65, so at least one of them must be
wrong.
5) Not really related to the previous four, but some kick towers are
labeled as stereo. What advantage would a stereo kick tower have? Double
bass?

Thanks in advance for any advice you can offer me.
