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.
