I use a Leki Trekking Pole, Mike. The height is adjustable, its very light, I use it as a walking stick, and just unscrew the knob to reveal a 1/4"-20 screw and locking thumb nut for the camera mount (or to mount a ball mount). Gear that performs multiple functions is a good thing when you're walking
.
I can't remember what it cost, but its probably in the $80 to $150 range.
