Only DIY if you have experiences with building good audio equipment.
Prefer large membranes or capacitors.
FWIW good large membranes are build by Haun, they are e.g. used for
Brauner microphones, but I suspect a large membrane only already does
cost more than 100,- if you only buy one and be aware that microphone
companies select parts like membranes, since not all do sound good, at
least not all dual sided do sound equal on front and backside. You have
to pay several to get one that is good.
All the microphone circuit diagram do look similar, it's the quality of
transformers, membranes, tubes or transistors that make a difference.
You don't need special capacitors and cables, such as Klaus Heine build
into microphones, I compared a good mic with averaged cables and
capacitors and with Klaus Heine voodoo. At best Heine crap does sound
equal, but it also can sound less good.
However, DIY assembly kits for 50,-$/€ is asking for trouble.
You may subscribe to the 64 Studio mailing list, IIRC Quentin Harley is
experienced in building microphones at home and perhaps he could give
you some tips, where to get good membranes and things like that, without
doing what companies do. Again, companies select the parts and they use
the less good parts for cheaper microphones and only the best for the
Linux-audio-user mailing list
