I have a like new/pristine 890S I bought new from HRO Plano 4/2019. Little use and from nonsmoking environment. Purchased the optional 270hz narrow roofing filter and Mars mod by HRO. Have all original boxes and packing, etc that came with it. Time for it to go, trying to determine what it should sell for.
Thanks for any suggestions,
Dan
