which makes me wonder, why is that..
There's a labor cost (which can be substantial.. something the "you can
build it yourself cheaper" doesn't always contemplate).
but it seems that I could build, for instance, chokes with decent coax
jumpers, some number of 2.4" mix 31 cores, and an enclosure of some sort
for around $20-30 in parts.
Based on my experience in the "low volume specialty equipment" business
for the entertainment industry, that would turn into a list price of
around $200-300, normally sold discounted at maybe 20-30% off that.
Maybe that's why.. hams won't pay $250 for a decent choke.
