I am going to be switching to Alienbees. I went with Calumet Genesis strobes. I think they take elinchrom accessories and speedrings. The Genesis have a higher output 200 vs. 160 and 400 vs 320. But the reflector dish sucks, and the modeling lamp makes it impossible to use grids, etc..
A shame, because the Genesis has a nice quality to them.
I'm selling them, and going either with Alienbees or White Lightnings (WL's are the pro orientated strobes from Paul C Buff, the same maker of AB's).
So, +1 for Alien Bees.
