I tried to look at Briese here in the US before I bought my first Para a few years ago. It was almost impossible to find much information, pricing, etc.
I have the Para 220 and Para 170. The 170 is a great light for location, a little easier to manage than the 220. Never had a chance to try a 330.
I'd be interested to see comparisons with the knock-offs. It would also be interesting to see the output from the new Profoto's, etc.
I *love* playing with all of the unique modifiers. Hard to do in a small town though (Ann Arbor, MI) No rentals here, and I hate to bother the reps for test units if I know I am not going to buy.
