I'd been persevering with an aging Optoma H79, mainly due to the colour quality (amazing skin tones and deep blacks)...
This had cost over £2000, albeit 6 years back..
The HD200X is a good replacement, at the price, the 1080i/p image quality is amazing, with correct (i.e. low) ambient light, the blacks are better than I was expecting for this price..
It handles blu-ray amazingly, beign used to 720p, you really notice the difference here.
If your main use is gaming and the odd film, you cannot go wrong with this.. It appears Optoma have packed a heck of a lot in for this price..
Throw ratio isnt super short, Ive got about 3m and if still fills a 90" screen, so use the guides available online to work out your distance.
Noise levels, I don't notice much difference to my old Optoma, and on cooldown, it blasts, so Optoma have definitely thought about the issues with overheating..
1) make sure you spend some time with calibration, out of the box skin tones need to come down a little..
2)if a replacement, watch out for ceiling mounting, you need M3 screws and a much smaller mount than the old school projectors, but I managed to use a Voges mount (with none of the arms) and its fine..
