UPS for Projector

[MalickT]

I worry my projector lamp will lose lifetime or die because of power interruptions. I have full blackouts sometimes for seconds. What UPS do you recomend that will power my plvz1x and PC for any power interruptions. I know there are special UPSs for projectors and they are called HT-UPS but in my country they are not for sale, only UPSs for PCs moustly. What do you recomend?
My projector uses 210W of power (135W lamp). Im allso looking to buy low-cost UPS but it must do the job!

You need a "true sinewave" or "pure sinewave" ups, both are
the same thing, the cheap computer UPS has a "modified sinewave"

I tried the cheap ones and when the power was out the projector
would start to flicker and I could hear a wine or buzz from the
ballast

I found a "true sinewave" UPS and it runs perfect

there are no cheap "true sinewave" UPSs - unless there on sale
or used :
