First the firefighter forums and now here? Anyways....
I use a Pro-96(portable), and it seems to work without issue, but I am on the Western Side of Hamilton County. These usually go on sale at Radio Shack in Oct/Nov, and then you can put it on a new Radio Shack credit card, and save a bit more. I know that the Bearcat one works as well on the system. We have a friend who is a cop and has one of those. I am guessing it is a matter of personal preference and how much you want to spend. Chances are you will get equal votes from people on either model, based upon their personal preferences.
