        I really doubt adding another '0' to the price of a K100D would be 
able to make it a cost-effective design.  Even if everybody who wanted one 
and was willing to pay for it (that'd be you and maybe 10 other people on 
the planet), it'd probably have to cost $20K to make back the engineering 
costs.

        It's a similar thing to aircraft avionics.  What amounts to 
basically a well-built CB radio costs $2500 new.  A similar model 
costs $1000 for a used one that's 25 years old.  The few companies who 
produce these low-volume devices charge a lot more than what they would if 
they were commodity.  In some cases (like portable GPS's), for almost 
identical hardware to a consumer-grade on that costs 1/10th the price.
