Murata make small piezo rate gyros at about 30 pounds each.
However, they are 'rate' gyros, so it would be quite tricky
to make an attitude sensor with them (drift etc ...)

Since you talk about a hovercraft, presumably it operates
in a 2d plane only, so I would have thought that a flux
gate compass would have been ok. Articles on how to make them
appear from time to time in the UK (and presumably the US) 
electronics press, if you can't afford to buy one.

One source that hasn't been mentioned here before is the
units made for Marine purposes, which have NMEA outputs. At
least they are waterproof !

regards, Dave
