I don't think it was the Broncolor Scoro pack you were seeing at those prices... I have a few of those in my rental inventory, and while they're amazing pieces of equipment (who would likely be totally overkill for anything you're doing), they also retail for just over $12,000 on B&H. That's pack only.
Are you sure you didn't see the Senso? I just got a pack and two light kit in for demo, and personally love it! It's essentially Broncolor's response to the Profoto Acute system. While it doesn't boast the same amazing flash duration as the Scoro packs, it's a greatly versatile pack system (much more assymetrical control than a Profoto Acute).
I'm personally a pack and head system kind of person, and I love the Broncolor lineup. But if you're just starting out, monoheads are an easy way to go. I personally don't like the Paul C Buff line, but they are incredibly cheap for a workable light. If you're just shooting for yourself, it's a logical way to go. Big downside I see is that if you ever want to rent a particular modifier, you'll have a hard time finding anyone who rents them.
