I use this Epson projector:

I bought it for 31k
It doesn't have any apps or smart features, you'll need to plug something in via HDMI (I use my laptop). It's got good colours, is relatively quiet and good (manual) keystoning. PPI is low so it isn't great at handling tiny text (eg., UI in video games) but that is to be expected at this price range.
