The lamps are not difficult to replace, you nowadays don't even have to remove the beamer from the ceiling or so.
Now spending $150-300 every two-three years on lamps isn't so nice. (Often the lifespan they give are too optimistic and assume using Eco mode.) But that wasn't the reason I didn't get one when we were considering this 100" setup.
So we were looking at a 4K Beamer which should also support gaming. Then BenQ with DLP had somewhat better options than Epson (LCD), quality wise and less noisy. But it still needed a darkened room. As well as good audio equipment. And the position and distance of the projector was not ideal with a rather complicated cable installation. (Even if there is wireless HDMI). Also, a white wall is never as good as a screen. And a fixed and tightened screen is almost needed since the ones you lower and pull up are not straight anymore over time.
So it became a 65" TV instead.
