Currently I have a Point and Shoot Panasonic DMC-TZ5, which is a great camera but sometimes I would like the ability for a better flash and/or an off camera flash. So with the lack of a hotshoe I thought it was hopeless, then I discovered Slave flashes. So I have been looking at a slave unit for additional camera flash (with bracket) and/or an off camera flash (I think that would be fun to experiment with). So my question is what is a decent slave sensor and flash with a budget in mind? Is this something I could use for fun or am I throwing my money away? I was looking at http://www.amazon.com/Sunpak-Digital-Preflash-Cancellation-Socket/dp/B000SJR7ZY/ref=wl_it_dp?ie=UTF8&coliid=I1WTWX5ORXB46B&colid=M1HMFL5UE7DC for a slave.
