Kogan F800 Projector seems to be at a good price at the moment.
Previous deal post by @Castcore does a much better job than I could at describing it, this is the previous post link with all the info and comments on it:

Apologies if there's a better way to list this, only my second deal post.
This projector is known by a few different names, it's a rebadged Elephas Q9 LED
I've ordered one, mainly because I wanted native 1080P and it's hard to find at this sort of price. I'm not expecting it to be amazing but I'll only be using it for occasional outdoor movies on the deck at night, projected onto a proper projection screen so I think it'll be ok for a fun thing to do. I'm not a serious projector user.
A couple of reviews I looked at before I bought it:
