I'm looking for some advice about the purchase of a real entry-level projector. I know what I'd buy if money wasn't any object, but I'm asking for something very, very cheap. I understand quality may be very poor at low price points, but I'd prefer not to have a flood of "don't bother if you can't buy a £4.4K Sony" responses, beggars can't be choosers. Should I avoid the low end altogether and look s/hand, and if so, what should I be considering, and what should I really avoid? Your help is greatly appreciated as always.
