Ok Im new here so please bear with me. I have an ARC-LS LED FIRST RUN # 1820 with both the 123 and aa battery tubes that I am thinking about selling but I am wondering how much $ I should ask for it and where do I post it? I saw on some other link that if I do a best offer I cannot post it in the marketplace but that there is some cpf auction. Anyway thanks for the advice. PS....I cant wait for my jetbeam m1x!!
