For decades condenser microphones have been the staple for high-quality recording and live sound assignments. Unfortunately, not everyone can afford to own a good one. Well that's about to change. I've written this article so that anyone who wants a great condenser mic (or those who just want more of them) can have their wish.
For around $20 (US) anyone can build an extremely accurate, life-like condenser microphone. DO NOT let the cost fool you, this mic's frighteningly good performance will blow your mind — and it's easy to build! -Joel Cameron
This microphone is largely based on a posting I found on the internet showing how to modify Realistic (Radio Shack) PZMs for better performance. I have simply finished the design so people can build a complete mic from scratch. After making a pair of these, I was shocked to find out how amazing they sound. In fact, these little buggers have become my first choice for capturing unhyped, totally natural stereo images, beating-out pairs of choice small and large-diaphragm condensers, and some nice ribbons too!

IIRC, those Panasonic back-electret capsules were discontinued about 6-7 years ago. Things changed since 2012 and today $60 will get you a pair of crappy Chinese electret mics at retail [sweetwater.com] while all the studio classics have been cloned.

I've heard that the biggest difference depends upon how you get the sound out of it. If at all possible, if you can't get audophile-quality cables, at least grab a high-quality coat hanger. If you work in a TOSLink chip to your design, then for God sakes don't go do all that effort and not get the gold-plated fiber optic cables!

Cannot deny but audiofools are a different industry. [audiophile.rocks] If you're building or maintaining professional audio recording equipment, you start here. [ap.com]
