Also, look at used stuff.
Anyways, what's your budget? Elinchrom is mid level stuff, imho as well as something like the Alien Bee/Paul C Buff Einstein light, but you're looking at $500ish or so a light for a 500w/s-650w/s light. There's also the cost of modifiers and stands. Expensive lights on cheap stands is not comforting. With adapters and speedrings and everything, I've spent over $500 on a strip box and an octabox. I still need to purchase another strip box. You can buy cheap modifiers, but cheap modifiers may fall apart or just not look as good as a quality modifier. How are you going to carry everything? I spent about $300 on a Pelican case large enough to fit my packs, heads, and cables. That doesn't include a way to carry stands and everything else. If you're shooting alone, you need a way to carry everything.
