Thanks, yeah thats the one I had seen of Benq. I have a 1620 right now and an NEC 3520. I wanted to replace the 3520 cause I am selling it to a friend and buying a new one for me. I saw bad things about the NEC 4570, so that one is out. Also Liteon hasn't been on my favorites list for a long time now. So then I guess for me, its 1650 meets little brother 1620, though can they run together , one slave, one master without problems?
