There are these from the Bay Area Craigslist (search Manfrotto or Bogen):
Photo / Video tripod Bogen and Tiltall - $60
BOGEN TRIPOD - $150
They both have geared center columns, which is rather essential. They are photo tripods (which you want for the geared center column), but big binos like video heads for smooth panning, so replace those photo heads. I have a 501HDV head listed here to replace the photo heads. I would start with that $70 3051 in the first ad above if you want it now. Check whether the height will be okay for you. Extend the legs out and test the center column to its full extent and back down before putting your binos on it. The leg angles can be adjusted to gain a little more height. Big bino risers are available too, which are suposed to help when adjusting the IPD for close-eyed ones.
The Bogen 3036, 3046 became Manfrotto 475B, which are the ones I have. Waiting for one of those shouldn't take too long in the Bay Area. Video heads to wait around for are 501HDV and 503HDV. Stay away from the plain 501 without the HDV; they will cause you trouble with stiction.
