And it's REALLY difficult to know if any particular USB adapter will work or not. Those marked "For PDA Use" usually do not work. Those marked "Belkin" tend not to work (though one person found one model that did work).
And $21, $24, or $29 are pretty typical prices. You're definitely not going to be able to 'build your own' for that price.

I’d say that the best answer is manufacturing volume.
The USB to 232 is mass produced while the “tool style” USB to serial devices (USB2SER, PropPlug and PropClip) are more specific and produced in small runs. In this case, volume affects the cost more than just the BOM (Bill of Materials) of the product itself.
I hope this clarifies why
