I have an Iiyama Vision Master Pro 450 I may sell. It has a very minor problem of not keeping the screen size though. It show a quater inch of black on each side after turning it off and back on. It is under warranty though. I will probably send it in for RMA soon. I would like to sell it before or after RMA which ever you want. I will give you an excellent deal on it though either way. Let me know if you are interested.
