You're joking surely ? The 'semi-pro' products widely available are so
competitively priced that attempting to make money by manufacturing them is
difficult.

I did this 30+ yrs ago when there really was a financial reason.

If you don't understand the circuitry don't even remotely consider trying. The
stuff on sale is pretty high performing and you won't be able to make anything
comparable if you don't have many years of design expereince.

You would have trouble even sourcing some of the key components ( like ultra low
noise input transistors for the mic amps ) and would have to pay extortionate
hobbyist prices.

The commercial stuff also comes in a nicely finished tough case with decent
controls and has been tested for electrical safety.
