Frogman, if you have the FZ30, you can save money and buy a flash from Sunpack. I believe it is called the 383. It is an excellent flash and it costs $80 @ B&H and u probably can find it for a lower price. It can do bounce photography like in Greg's pictures. The other flashes are more expensive partly b/c of the TTL feature, which is pretty great on any camera. But our FZ30 doesn't have TTL, so to buy a TTL flash you are just wasting your money, unless you plan on upgrading to Panasonic's new cameras.
Thanks Hank. I went looking for the Sunpak 383 to no avail. I live in Australia and it seems that this flash is not available here. Is this a recent model? Going to Singapore in the near future. Maybe available there.
