	How are these things resolution/accuracy/repeatability-wise?  Esp.
in view of the fact that robots tend to have metal and other things in
them and around them (particularly in labs with lots of computers)
generating anomalous magnetic fields?

	We had not real encouraging results with the old Radio Shack model.
Are the more expensive ones better in this regard?
