Motorola XTS4000 vhf

ISO a Motorola Xts4000 VHF. About 5 years ago I owned and stupidly sold my xts4000 ( nextel looking) radio. In fairness I needed money but really like the radio. Hated to part ways with it. Does anyone know of any wholesale or Govt sales or trade ins that may have these radios as used or new old stock ? I work for a fire dept and assigned to Marine Operations. This radio has a perfect application to Monitor USCG analog and digital plus local fire dispatch and Natural Resources police.
