Flashpoint XPLOR 600 HSS Battery-Powered Monolight with remote for $423.
I just picked up a second one. I have one and it is a very good strobe. I suggest adding in the extension head for $64 (when purchased with strobe) which takes the weight off the light stand on top and hangs the strobe down low.
