I'm a little late here, but having taken both the XA and the Stylus Epic with me on vacation a couple of months ago, I have to say I'm very disappointed in both - within a day of carrying them around in my pockets, both broke - with the XA, somehow the film winder release button in the bottom got depressed, I didn't notice and wound the film, which has jammed the shutter release (opening the door, which normally pops the release button back, doesn't do anything), and with the Stylus Epic, when I try to take a picture, the lens adjusts as it normally does for the AF, sticks in the outward-most position, the shutter goes off, and then the camera appears to power off (lens still extended, display goes blank), but if you wiggle the clamshell lid it resets temporarily.
Both of these were in my carry-on for the trip there, not dropped, and worked before I left.
I haven't looked very hard yet, I'm hoping the XA might be fixable because I actually quite like the lens quality as well as the automatic +2 EV backlight switch - but I'd think twice about bringing one with me travelling again.
Speaking of small(-sh) rangefinders, I'm considering getting a FED-2 with a collapsible 50mm lens - entirely manual, made of metal but by most accounts not that heavy, and fairly compact with the lens retracted. This also has the advantage of not being terribly expensive and reasonably common, so if one breaks, a replacement is readily available. The only real downsides are a lack of a meter (time to practice Sunny 16!) and limited shutter speeds of 1/30 - 1/500 (but on average I can't handhold well below 1/30 anyway).
Anyway, just my $.02.
