For $120, I can't help but recommend the Metz mecablitz 36AF-5 Digital Flash for Olympus / MZ 36352OPL . GN 36 and quite powerful. it is essentially a full-sized flash for many indoor situations. It comes with a small stofen-like diffuser that fits right over the flash. Additionally though, I use a stofen on it and bounce it off ceiling.. Recycle times are *extremely* fast (using Lithium AA batteries, never miss a shot as they recycle within nanoseconds it seems). Provides even fill-flash and lovely effects for the non-pro (or perhaps pro). Here are two images with E-P3 and PL 25/1.4. First, I had wacky lighting going on... indoor photo, harsh sunlight from large bay window to right of photo, plus overhead tungsten lights.. and the flash helped make 90% of those lighting issues go away. And here is another taken in a VERY dark room at night (same birthday girl, a few days earlier).
