My daughter is eyeing an Optoma DV-10 refurb for her dorm room. She has gotten hooked on front projection at home. Limited budget but at under $500, these fits the bill. Has anyone had any experience with DV-10 refurbs? I remember that the DV-10 had some early issues that required a factory return, so there may be a reason these are on the market, but I'm a little concerned. Would they normally be factory certified, and would the bulb be new? Ther eBay seller, bigcitydirect, has over 2000 feedbacks, overwhelmingly positive. How spooked should I be? Thanks,

Kevin
