I'm looking for a tripod that will fit in a carry-on bag and hold up, for example, a 35mm AF SLR or maybe a medium format rangefinder. Lightest weight is not important as value. What names and models should I be looking for on the used market. I don't have the budget to go out and buy a new carbon fiber wonder. I'm more looking for the "tiltall" of smaller tripods, in terms of value.
