A good stock mic that I have found is the older uniden bearcat mic. Not the new chrome grill space age ones, the silver front, black back regular looking mic. It has some very clean and clear audio for a stock mic, I've used it on a lot off different radios including my Icom 746, and it sounds good on all of them, not the loudest one I have, but by far one of the cleaner sounding ones. The road devil mics are good but if you can find an astatic 575 they are great mics, used to have one and they are getting a bit too expensive to purchase these days. Anyway just my 10 pennies. Have a great one and God Bless.
