First, the Pro-163 is ready for rebanding by having the 700mhz frequencies in it. Second, it has more search ranges than the 2055. I own a 97, and there is a definite difference in reception. Third, Ulster Co. is populated with three EDACS systems. The two that are for cities in the county are standard EDACS, the third which covers multiple sites, counties, and cities, uses AEGIS. It is a proprietory digital system just for EDACS. Your county is on that system, but uses analog TG's, so you will be able to monitor them there. Also, you have a few conventional frequencies to monitor. All, in all, the 163 is a good choice for your new scanner. Looking to get a digital will not let you monitor the digital TG's for New York state, or the digital TG's on the AEGIS system. Railroads, milair, and other conventional frequencies are out there to be heard. I've had my 163 for over a month now, and it runs all the time when I'm occupying my radio/computer room.
HTH,
