John, they're common as dirt -- $25+ at the FLAPS to as much as you
want to pay for a marine one with gimbaled sensor.  I just bought one
for $6, closeout at BJ's Wholesale Club.  The recent ones are
self-compensating, just throw them in calibration mode and do a slow
circle while they map the deviation curve (it's a sine wave, one
cycle, so they can do that).
