I've done a lot of Web surfing and found a number of linear postion
potentiometers.  The problem is they cost more than I have invested in the
manifold.  Regular audio linear potentiometers do not have the mechanical
range I need.  I need a position indictor that has at least 5 1/2 - 6" of
travel.  Anyone have any ideal where something reasonably priced might be
found.<<<

Contact the folks at Menzimer (aka MAC servos).... they have a linear sensor that is reasonably priced.  It is a bit shorter than what you're looking for, but a ratioed lever operator would be the easiest and most positive setup you could come up with (IMHO).  BTW, they also have an LED ladder readout that matches the output of their sensor.  We're using one on that LIVP I'm working on to track the movement of the radiator nacelle door, and it works great.
