You can build it yourself and here's the shopping list, all available at any hardware store for under 10 bucks:
* 3/4" SCH80 PVC pipe - enough for 2 pieces: 47" for pole & 6" for handle
* 3/4" PVC pipe caps - 4 ea.
* 1/8" clear vinyl coated steel cable - about 6'
* 1/8" cable ferrule and stop set - you'll just need 2 stops
* 1" black Velcro strap
Start by looking at how this one was made-it's the same general concept-and comparing it to the CHP version:

The construction differences are that the CHP version uses no copper reinforcement piping, the cable end at the loop (business) end of the snare pole is swaged inside the pole instead of on the outside and the cable enters the handle at the end instead of in the middle of the handle so it forms a straight and not a "T" handle. That's about it.
