B&H has the full kit for only $1550 which includes 2 500 watt monolights, skyport wireless transmitters, 2 softboxes, light stands, sync cords, and cases. I want this kit!
You can save $100 by getting this kit, which is the same thing except a 500/250 watt combo instead of two 500’s. However, I think it’s worth the extra $100 for the two 500’s. If you are really strapped for cash, they even offer a two 250 watt kit, but I think you’d be penny-wise, pound foolish getting that kit as you’ll grow out of it quickly.
