Well, there are advantages to both, the interfaces that plug in to the back 
of the radio, can get the voice in, some pins are setup for that, but the 
problem is, while you're doing that, the mic is hot so it will probably pick 
up sound form in the room, I know some radios do that, most in fact I don't 
know which ones specifically, so you have to either unplug the mic, make 
sure it's a dead silent room, or hook up to the front mic jack like the rig 
blaster does. that's something to think about for sure, beyond that, any of 
them will do what you want, it's just a case of figuring out what other 
features you want and what you want to spend and I'd look at reviews. some 
of them are real RF prone, that's why I stick with the rigblaster series, I 
have yet to see a problem with them.
