Ordered this on 13/07/12 from Amazon, not in stock at the time but arrived 26/07/12 - no complaints.
Bought this for my Panasonic Lumix DMC-TZ30 which I'm more than happy with, the only fly in the oitment is the woefully underpowered flash. Using the Sunpak PF20XD makes such a dramatic difference to my indoor shots I reckon it was well worth the £60 I spent on it. (I see it has just gone up in price!) It's one of those "it does exactly as it says on the tin" deals. It works with the camera's aperture priority & manual settings (although "face recognition" has to be switched off - underexposes without subsequent adjustment), adjusts for pre-flash (which can be swithced off in the TZ-30 anyway) & you can adjust the aperture/power output as you'd expect in any regular flashgun. I'm glad I bought it, in fact I wish I'd bought it sooner to use with my previous digital compact.
