Figure 3$ for E6 film and $5 for developing. You'll need to shoot well over a hundred rolls of film (~4 thousand images!) before you break even. (FWLIW, I shoot maybe 20 rolls in a typical monsoon chase season.) Low cost cameras are also nice in that they are somewhat expendable; if a gust of wind knocks over your tripod, you're out one hundred bucks or so, not seven+. Rain, blowing dust, etc. are also less of a worry. Throw in $ for data cards, a backup battery, etc., and 'cheap digital' starts to become somewhat less of a bargain.

Actually I ran some numbers. From tracking my shutter count in 1 year I shot 4550 photos(yes I know this probably more than I would shoot without film). Using the cost esimates from above that's ~$1011 I should have spent on film assuming a 36 roles. That means I've almost paid for the camera. When it comes down to it I think digital is cheaper in the end, and with lightning photography it allows you to shoot more for that unlucky shot that you might not try for with film because your thinking of evey penny your throwing away if you don't get anything on film.
