Rogue: BSIC/ASPN/FPPC At one point, I've owned all three and feel that these are NOT grossly undervalued where they currently trade ("10 bagger potential"). If your time horrizon is that long, IMO TVOC.OB has best potential for a very significant return. TVOC is definitely the most undervalued based upon earnings, cash flow, and reserves.
