Two Cameras--200 USD.

That sounds expensive for two second hand 35mm cameras with pretty
basic requirements - a tripod screw thread (for ease of mounting), and
auto wind-on. *Is b&w film acceptable? *If so a developing drum is
cheap again of Ebay.

However I can't think of a single reason I'd want to do it that way.
If nothing else looking at the trace from a flight recorder can be
very interesting, though I conceed that if you are not bothered about
it being valid for claiming badges, just about any Garmin GPS can be
plugged into a PDA running free software giving a cheap way of
recording flights. *My club provides barographs (EW-B) for all club
single-seat gliders which does for Bronze (if not done by direct
observation) and Silver badges.

The Willamette Valley Soaring Club has an older Colibri available to
any member to use. We also have a number of Palm/GPS setups in the
club that are used for "recording" flights. In several cases the Palm
units are cliped to a GPS unit that clips directly to the unit and
also provides power for the Palm. Very convenient and easy to move
between gliders.
