ALL projectors are compromised to some degree. In chosing one you'll have to narrow down what is acceptable to you and this may include motion artifacts, throw distance, noise, screendoor, rainbows, price etc.

By all means use the forums for guidance but don't base parting ££££ on OPINIONS (esp over the pond) over YOUR OWN EYES.
