I'll agree - but perhaps the main reason is that
modern components are
almost impossible for the home builder ... and only the odd few (Tony? :-)
Impossible? How?
want to spend lots of time and a fair bit of money to
build something that
is usually less capable than a less expensive commercial product.
There are two good reasons to DIY. One is for personal understanding
and in that case practical is often not the point. Two is something
specialized
that a commercial peice that may be expensive or a poor compromize.
I happen to build, RF, AF and digital and the economicas is that I have
a very deep junkbox and parts supply to exhaust doing it. I the realm of
radios (transceivers) I have several I've designed that far exceed
commercial
gear as I could specialize them.
Generalizing on DIY/homebrewing is not good as exceptions do abound.
