You can see what I own in my signature, however, I can't overstress how much I regret starting out with Manfrotto's RC2 quick release system. Do yourself a favor and get a head that uses the Arca-Swiss style quick release clamp and plates. (You'll see it referred to as the "arca" or "arca-style system also.)
It's tough to follow this advice, at least, it was for me. I've done much better following advice on cameras, lenses, CPLs, etc. For some reason, I didn't listen to the wealth of knowledge here when it came to tripods and tripod heads. As a result, I just placed an order to change over everything I own to the Arca-style plates. It wasn't cheap. The reason? As far as I can tell, you can't get any of the Manfrotto heads to stay where you put them after you tighten them down, at least the ones that use the RC2 quick release system. They all sag. The one I have is excellent when it comes to locking the ball in place. It locks down tight with very little force and the lock is positive. The problem is in the connection between the camera and the quick release plate. There is also a less than stellar connection between this same plate and the clamp itself. As a result, you are constantly trying to factor in the amount of sag you will get depending on which lens you are using at the moment. Believe me, this gets annoying after a while.
Even if you get a cheap tripod head, do yourself a favor and choose a better quick release system than I did, i.e., get the Arca-Swiss style.
Sorry for the rant.
