Coming at this from another point of view, I think a lot of people especially newbies shooting portraits think that they need a bunch of lights to get good work. They see pros have 4 or 6 lites and think that they will need that too. Well maybe, but starting out most people don't have a clue where to put them anyways and if they started with just ONE, they could learn to light, and later on they could add more.

With that in mind you can pick up used monolights for probably half what they cost new. It's a great way to start and after a while you can have a set of great lites and not a closet full of cheap stuff that you bought once because of price.
