I am considering to purchase a studio strobe around 2400watts power. I went B+H in NYC and checked a couple of different ones such as, Comet, Sunstar, Speedtron, and Prophoto. But, I didn't really get their differences besides a number of plugs to be connected to the light heads. Also, their prices are almost same(around 1500 dallers). Can anyone recommend a good strobe? I don't use many heads--most of the time 2 heads are enough. And, I don't want to get heavy one since I go on location often. Also, I don't want to spend a lot of money!! thanks ric
