I use an Icom F5021, essentially, what PCI sells but as mentioned, they are pricey. I have been able to buy a couple of used ones on eBay like this:
<p>Icom F5021 Mobile Two Way Radio. </p><p>50 WATT VHF BASE STATION!! 128 channel. </p><br /><p>The Icom IC-F5021-66B (formerly IC-F5021-51B) Base Station is a special product by Icom that combines an Icom IC-F5021 VHF 136-174 MHz mobile radio and a power converter in a custom aluminum housing...

And they are cheaper, but one of the 2 that I got had a bad mic. Fortunately, replacement mics aren't too expensive.
I should note, if you go this route, you will need to have the radio programmed. I do have the software, cable and channels you'd want and can help with this but I would have to do it in person. Maybe a future suds-n-grub or something? LOL
