Have a look at
Feisol, while you're at it. I spent months trying to figure out what I wanted vs. what I wanted to spend. In the end, I still ended up spending more than double my original budget (which was unrealistically low for what I wanted.) btw, that Thom Hogan article that r.harris1 linked to is a good read and also a big part of the reason I expanded my budget.
After using my Feisol for more than a month now, though, I am extremely happy.
Specifically, I went with:
Feisol CT-3472 Elite Tripod
Feisol LB-7572 Leveling Base
Really Right Stuff BH-55LR Ball Head
