If you want to be able to listen to anything, digital is the only option. Fulton already has a bid out for a consultant for a new P25 phase I/II 700/800 system to replace the 21 year old Smartnet II system in use now, so it's only a matter of months to a couple years before they finally retire it, pending funding sources.
I have a Uniden 396T, but side by side with a friends' PSR500, the PSR hands down excels at decoding P25 CQPSK-LSM simulcast (which is what every P25 trunking system except MARTA uses). Audio is excellent. Sure, the PSR is a step backwards as far as the UI, and isn't as cool looking as the Unidens, but in the end of the day, it receives better.
And in the end, that is the whole point of scanning, to listen, not spending $500 to have a nice bookend.
