The non-ETTL version is going for $299 right now and = 5 or 6 Canon 600s as far as power goes. The light is very good. I have 7 Canon 600s and have not used a one since getting the streaklight. Very good for outdoors too.
While very portable, such units may limit you in the diffusers choice, especially the larger ones. Unless you need easy portability and outdoor use, I would use a studio monolight.
I have not run into any problems with any diffuser. Use it with soft boxes and umbrellas (72"). Works just as easily with my modifiers as the Canon flash. I wish I could afford two more. I should probably sell my Canon flashes to get them. I really am that happy with the Streaklight.
On sale right now for $249. wow.
