Well, the real thing you're leaving out of your comparision is the seccond trip to china. Once you've paid for your digital camera, continuing expenses are zero, or the cost of prints. Once you've paid for your film camera, the cost of taking pictures stays as a per shot expense. If we're keeping this a closed one month long trip thing, then check out the resale value of the $500 digital camera and the compact flash card after 1 month. Damn I'm glad I don't work for Kodak.
