mporter012, the other posters are right. Your specific intended use makes a big difference. Medium format cameras vary greatly in weight as well as mirror/shutter vibrations. TLRs have no mirrors. The Pentax 645NII's mirror is so well damped that it doesn't even need mirror lockup, and the Pentax 67II's shutter is so violent that even with MLU certain lens/tripod combinations lead to blurred images. Leaf shutters are allegedly less vibration inducing than focal plane shutters.
This is an interesting article that will guide you in your decision making process. It was written in 2003 so the equipment names have changed but it still gives you an overall idea about some of the pitfalls to avoid. The author came to the conclusion that you should get something in the $800-$1000 range. A lot of his advice seems sound. Unfortunately I don't shoot enough to warrent spending $800 on a piece of equipment I only use a fraction of the time. It's nice to daydream of the ultimate tripod but instead I went inexpensive. I went inexpensive but kept some of the things the author said in mind. I eventually settled on a vintage Star-D. It is one of the nicer ones that seems identical to the Tiltall's of the same era. Except for the large handles it is all aluminum and brass. I got it for about $70 on an auction site. It is in really nice condition. So check out vintage Tiltalls if you want a solid work horse that has decent resale value. If you find a good condition vintage Tiltall at a reasonable price on Craigslist or an auction site I would get it. The beauty of it is if it doesn't fit your needs you can sell it and you are only out a few dollars... or you may break even.
The other thing to consider is you often have conflicting needs when you get a tripod. The best tripod would be heavy to form a stable platform for your gear. But it also needs to be light enough to carry as far as you need to carry it. If all you are doing is studio work you could buy a gigantic wooden tripod. It would be heavy and have good damping properties. But if you need to hike up a mountain then you need something lighter. I guess my tripod is 6 pounds including the center column. Some people pay feel that is heavy. It works for me and I hike a couple of miles away from by car on sloping ground with it. My backpack full of medium format, DSLR, and sometimes 35mm camera equipment along with my tripod would break my girlfriend's back. So you have to realistically figure out what works for you.
