Oops, that wasn't intended as a rant at you Lance Jackass, although it probably looks that way.
I feel quite strongly about the issue of the right equipment for the job, and the fact that often it is made all to easy for innovative and practical concepts to be smothered at birth by bureaucrats with little understanding and even less interest is fraustrating to say the least.
So apologies for any offence I may have caused, and I will allow this thread to return to it's original course.
