If you are planning on scanning and staying in the Chas Area, then it might be a wise decision to save money and buy the digital scanner. In Mt. Pleasant the police and fire dept have moved to the county digital system. Along with just about everybody else. (NCPD, Chas Sheriff, EMS,ect).
Right now the only analog systems are the Palmetto 800 in the tri-county area, and the Chas City Police and Fire Dept on their own system. It is only a matter of time before they all switch to digital.
As far as a scanner, I agree with an earlier post that on the Chas County Digital System the Pro-96 has a hard time decoding it. The PSR 500 does a better job, in my opinion, but. it still is lacking in perfect comms for this system. The PRO 2096 is the base unit for the Pro 96 and the PSR 600 the same for the PSR 500. The Cheapest I have seen on the web for the PSR's have been 449.00.
Hope this helps. I should add that I do not have any of the Uniden Digital Scanners so I am unable to comment on them. But reading posts in the SC Forum it would appear that all the digital scanners are having a "rough go" at the Chas Digital System.
Hope this helps
