其實部機咁耐真係要博一博，
依家全新1080 投影都係七八千，會不會考慮？

I think he has a very good point.  

Sometimes problem of projectors only show up when it is fully warm up, and you cannot go by the bulb hours anyway since many can be reset.  

If you must, check for convergence, play movie for at least 30 minutes and switch sources to see if there are screen lock ups, general sharpness (very subjective), irregular bright or dim corners or weird colors, then again, without knowing how that projector perform when it was new it is hard to determine if you are buying a 'lemon'.

I would pay a bit more and stay away from 720P product, after all it is already obsolete and 1080p sources are plenty and affordable, best not to resample incoming video signal.

720 is already time to rest ,isn't?

呢部打機仲叫做可以，不過睇下玩咩，要靚畫面同睇戲就一定唔會揀呢部！

A used Panasonic AE4000 is also around 8K, I bet its quite a bit better than that Optoma.
