I am 6'3" and found a dynex dx-sw040 that is really a bit too tall for me. I was in the DC area and going to the Udvar-Hazy Air and Space Museum near the Dulles airport, after a set of meetings. I found that they do not allow tripods, but allow monopods. So, this was a spur of the moment purchase at Best Buy for about $30, the night before. I just used the head from my tripod. It has a 1/4 bolt, so you can use a 1/4 to 3/8 bushing if the head needs a 3/8 bolt.
It's nothing special, but it works just fine. It easily holds my K5 with a DA 60-250.
With it being a bit too tall, I just don't extend one of the leg segments all the way. It has flip leg locks.
