I have been offered a used (450 hrs.) 10HT with Sony's ceiling mount PSS-610 and a 16:9 screen 198x110 cm for about 2.300 euros (I believe almost £1.500). As I'm new in the projectors area I have a few questions. 1) Assuming everything is ok, is this a good price or should I look at a newer projector (about the same price)? 2) Does anyone know how much does a new lamp cost and can it be exchanged by me or does it have to go to Sony? 3) What should I look for when inspecting the projector and it's image? Thank you all.
