The 2 dealers I deal with, and I who have no financial gain from are Rail-Comm of Memphis,Tenn, and First Communications of Florida. We have a contracted discount with them. Maybe if your state has a bidder contract use them. We paid about $700.00 for Mobiles and Portables and $1800.00 for the repeater.
The point has to be made, are you replacing an analog Public Safety grade radio with digital PS grade radio? Most every department I know of other than in the big cities are using Pro series radios. My agency uses PRO series, so does my local PD and FD, we have over 1000 HT-1250's, and CDM-1250's. They are not public safety grade radios in a sense, at least according to Motorola. Motorola would like all PS agencies to buy $4K radios. Our sister agency uses XTS-2500 radios, but the price difference is about 4 to 1. Motorola is also known for pushing any product that gives them an unfair advantage in the market. MOTOTRBO is that product at this time. MOTOTRBO is half the cost or less than a comparable P-25 radio. It does have a lot of nice features that go beyond an analog radio. So i wouldn't push the PS radio grade button only. Besides why would a small department need to buy $3-4K radios anyway, especially if they don't need any of the extra features. If an agency wants to go MOTOTRBO, or even NXDN, let them, but I suggest they try a few radios in real situations and test it for themselves first.
I know of at least 2 departments that have gone MOTOTRBO, one with GPS tracking. That department has had a few problems, that were related to a bad repeater antenna and a timing issue with the GPS on the second slot. The other department just uses it with a repeater, and works just fine. There are probably hundreds of users of MOTOTRBO out there including large hospitals that are now networked with each other, those also have all worked just fine. My personal experience with MOTOTRBO is that the jury is still out. I don't like digital radio's, just like I despise digital cell phones.
Good luck with your upgrade!
