Surprised no one has mentioned this: Radio Shack is long out of business, (yeah, someone bought Radio Shack online but they don't sell scanners) and official support is long gone. Uniden is at least well in business, and supports even legacy products like the 996 as far as repairs. For sub $100 they will fix and repair the current and recent products. FWIW I have both an SDS200, BCD436HP and BC536HP, the SDS is clearly the true gem for linear simulcast, but the 536 has far better sensitivity on VHF air band and VHF high band. All excellent products. All fully supported by Uniden.
