Kogan F800 Projector seems to be at a good price at the moment in Black Friday sale.
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:

This projector is known by a few different names, it's a rebadged Elephas Q9 LED
I bought one when it was $259, mainly because I wanted native 1080P and it's hard to find at this sort of price. I'm using it in a bedroom on a stand where I can watch 100" screen in a darkened room and also for occasional outdoor movies on the deck at night, projected onto a proper projection screen. Just a fun thing to do, I'm not a serious projector user.
This projector is really very good quality for the price, bright and proper 1080P. There is one major problem, the fan is noisy. So noisy that I wear headphones when I watch stuff which is fine by me but it's noisy enough that it might annoy you. For the price though this is really the only thing I can fault it on.
A couple of reviews I looked at before I bought it:
