How many is enough?
Dave, be careful since you said you're "about to go" on a trip. Apologies if I'm stating the obvious to you..... Any new camera (new to 'you' even if its a used one) should be learned first, AND whether its new or used you'll have to be absolutely certain that it's 100% working and reliable. After all, what do you do if it breaks in the middle of your trip, or you discover a flaw? Or worse yet, you find out you took a shot or two of that flying saucer with the lens cap on. Other than that, you've received good suggestions for what camera to take. I agree that the XA is "good enough" for your trip. I'm still mourning the theft of mine from my truck (with A-16 flash attached) last September...
