+1 to the Olympus Mju-II (aka Stylus Epic). I carry 2 with me at all times (ASA 400 & ASA 125 or 3200). Very lightweight, fits into a hoody or jeans back pocket. I found mine at the local flea for under $10 each.

The auto-flash thing is annoying. Just remember to press the mode button 2x each time you bring it out to suppress the flash.
