Hey guys, just starting at a new ems agency and I need to buy a speaker mic. My old agency provided them but the new one does not. We use Motorola PR1500 radios. Are there any good third party speaker mics? The oem Motorola ones are pretty pricey at $70. Alternatively there seems to be some Motorola models on eBay but I don’t know if they or legit or even if used is a bad idea for these things. Thanks.
