Elinchrom has a wide variety of light shapers at very good prices and they're very easy to set up. That being said, the Elinchrom mount is just horrible. I recently rented a couple of Elinchrom's for a job and when I was setting up the lights the cover for the flashbulb just wouldn't come off. It took me about ten minutes to get it off with a lot of force and wiggling. And all this in front of the client! Terrribly embarassing.
When I brought the lights back to the rental place and told them about it they said "Yeah, sometimes they get stuck". That would definitely not have happened with the Profoto mount.
Also, I don't know what line of Elinchrom monolights you're considering but the BXRi line is definitely not pro equipment. The light stand mount is cheap and plasticky and it struggles to hold the head in position with even a small 1x1m softbox.
