Yamaha DTXpress/DTXplorer/DTXtreme

Hi ppl

I've been getting about 50% triggering from my KP65 (discussed
previously here), and I took ppl's advice and tried changing the leads
and so on. I still think it's the pad.

I've a gig in September, and the deal is I get to send the KP65 back
for repair. Obviously there's a risk I'll be kickless for my gig, and
anyway, how do I practice in the meantime.

So I got to thinking, I'll buy another KP65. Since it seems to be
general knowledge it's not triffically robust, I thought having a
second would give me a good chance of a long life after Yamaha replace
the product and finally withdraw support.

However, my supplier is saying that Yamaha say there are none in stock
and won't be until September. I also started to think .. why am I
buying another unit of dodgy reputation?

So, folks, the question. What might be a better replacement? A Roland?
A Yamaha kick pad from the Xtreme or higher? Do they work? Any advice
or thoughts would be appreciated.

Cheers
J
