Yamaha DTXpress/DTXplorer/DTXtreme

Hi -

I have been a lurker here for a couple months and decided to ask a few 
questions.

I have a "vintage" TMX (all new circa 1994) that has always worked 
great, but I want to get a whole new set and am considering selling.  
Is there a market for these older Brains?

The set consists of 7 DAUZ 8" & 1 10-11" pads, two AXIS Analog Base 
Pedals with Piezio Pick ups, a KAT Hi-Hat/3 out put Hi Hat pedal, and a 
full sized Gibraltar Rack and Throne.

The TMX has 12 inputs - I excluded the DAUZ/KAT cymbal "sticks" as they 
are damaged from age, but the 4 additional inputs are there and worked 
great when last functional.

I have had this kit in storage for years - but it worked great and 
provided me many hours of great "full-size" play.

BIG QUESTION - is it worth $700 - $1K?
