Suggestions on best portable 500WS+ Strobe Kits

[jaguarmedia]

I have been searching around for a "Good-Great" Strobe Light kit that is both portable and easy to assemble and will provide the highest level of output for the money. My Budget is about 1500 but if there is a "SUPER" kit for 2000 I would probably jump on it if enough people suggested it.

I want at least 2 lights with stands, umbrellas, soft boxes and Batteries.

Your suggestions are appreciated.

I have looked at AB's and White Lightnings so far.
