I'm looking for something more potent in a strobe setup. I'm working on building a 12x20 portrait camera, and I need some serious watt-seconds to give me adequate f-stops. Right now I have an older Norman 2000 w/s kit, but I'm wondering what people would recommend for something a bit more modern with a bit more oomph. I did some shopping around on ebay for used kits, and I was seeing Balcars, Elinchroms, Profotos, Calumets, Speedotrons and Broncolors. Does anyone have recommendations for a system to watch out for? I'm operating this out of my house at the moment, so I don't have 40amp circuits, so lower power consumption would be a nice plus.
