Based on what is in the database, you should be able to suffice with any P25 digital scanner, Phase 1 type. In my 23 years of experience with P25 scanners, I would suggest a Radio Shack/GRE/Whistler type of scanner for scanning the Conventional P25 digital type that you'll need in the VHF-Hi band for monitoring. Some of the older, but still functional and more affordable type of handheld models to look into include the Radio Shack Pro-96, Pro-106, Pro-651, GRE PSR 500, PSR 800, WS1040. If you decide to go with Uniden model types, you can look into the BC250D, BC296D, (both the 250 and 296 types WILL need a separate BCi25 or BCi96 P25 digital card to be included), BCD396T, and Home Patrol 1 as affordable ones to go with. These are older types of P25 Phase 1 scanners, but they still do the job of decoding any P25 Phase 1 digital conventional type that you are looking to monitor. Research each type and see which ones will fit your budget. These can be programmed by hand or with software. I have no experience with programming the Home Patrol 1, so that one might need software to program.
As said above, if digital simulcast is used and depending on your location of where you are at, it might be better to spend the extra money to purchase an SDS100 scanner to overcome the digital simulcast LSM distortion (explained often on this website). The SDS series of scanners will run you in the $500-$650 range for purchase.
