You can't go wrong with Profoto. Most European strobes are well designed. Cheaper strobes are dangerous and the color balance can be off. I own some very old Broncolor Impacts and they're well made. Another thing to consider pack and head system or monolights. Monolights are heavier because the power pack is in the head so they will be harder too put on a boom. Systems with power packs have lighter heads and easier to control the power output on each head from the pack. What I did was to build a strobe system piece by piece. A set of strobes can set you back some serious cash. Another type of strobe to consider are just regular flash units on light stands. They're lighter and cheaper. I've seen some great results with flash units.
