I have to agree with 3D regarding the Meyer X-10. 

A consultancy where I last worked rented out their conference room to Meyer for a 2 day seminar and during my lunch breaks I was able to sample their products.  Came away thinking that they are truely obsessed with pushing the boundaries and their R&D is truely staggering.  This is a company full of guys with very, very big brains, trust me!

One problem, can anyone of us really imagine having them in a domestic situation?  I think that ATC's let us sample some reasonably good high resolution monitoring while still maintaining WAF.
