Yep, brand name, used.
In that price range I have bought one set of Gitzo legs without a head (figuring on finding a used head at some point), and (later) a Velbon tripod with two heads (P&T and ball). So then all I had to do was mount the ball head on the Gitzo legs and the pan and tilt head on the Velbon legs. The Velbon purchase came with two complete sets of QR bases and a couple of extra plates.
The Gitzo legs are quite heavy, but monster-grade sturdy. I usually don't take them with me, but I will take them on an upcoming family shoot. The Velbon legs are not what you would call "lightweight" by any means, but sort of in the mid-range of weight. I have a light-weight set on my wish list.
The quick-release (QR) mechanisms are somewhat proprietary, so do some research on the interchangeability of those plates. One "standard" that has come to the forefront is "Arca". If you start out with an Arca-compatible QR system, then it will be easier to find compatible attachments in the future. Probably Manfroto as well.
Then you have to decide what kind of head you want. Most used tripods will include a head, but you can be picky in shopping for used tripods, so look for the one you want. The prices should be affordable in any case.
