All current Uniden scanners receive NFM. The least expensive current Uniden handheld model that covers 800MHz is the BCD325P2 digital scanner at around $370. The least expensive current analog desktop/mobile Uniden scanner that covers 800MHz (including analog trunk tracking) is the BCT15X at around $175. Unfortunately Uniden no longer makes a handheld equivalent of the BCT15X.
If cost is an issue you could always look for a used Uniden analog trunking scanner such as the BC-246, BR330T or BC-346XT.
