Which one of these projectors under 800EUR (1000$)

Hi guys

I'm looking to buy a 1080p projector for my living room. There will be 5m (16.5ft.) max from projector to screen, and the room will be totally dimmed, when the projector is going to see use,

I'm slightly sensitive to rainbows (I see them, and they do bother me a little bit, though the only place I've seen them is on my friends OLD (!) presentation-projector, so I figure anything will be better than that).

I've been looking at the following models

Optoma HD230X
Acer H6500
BenQ W1060
(InFocus 8600)

These I can afford, and they all seem alright. I would, however, like to get your opinion on just which one I should go for? (If any of the mentioned)

Best regards!
Mathias
