We have two Epson 1505s =
laser/
LCD technology. They are - when we bought them - the best bang for the bucks.
We use them together to give us a 3840x1080 '
pixel space' across our back
cyc curtain, which in reality gives us a ~64ft x 20ft wide
image.
They look darn nice and have been mostly trouble free after many hours of operation, yet they have a quirk.
From my experience, yours might be different, matching projectors and blending them together *exactly* starts with being able to match projected WHITE.
With these Epson, everything we have tried to get the white to match, calibration, using their color tools, even sending one back to Epson,
we are unable to get the white to match perfectly and without that, you will never get them to match exactly.
That said, until someone comes up with a better looking or more powerful
projector for $13K, they are the half the price of a Panasonic and look better.
