Purchase advice and options

Location: Melbourne, Australia

Price Range: $300 - 500

Purpose: Movies and shows at night

I'm looking for options and buying advice for a projector suitable for a small studio space. I'm planning to set it up facing a blank wall approximately 1.5m wide in front of our bed. The room is about 3m long. As we cannot mount anything on the wall and the bed is directly in front of the wall - our only option is to place the projector off to the side on a bedside table or directly in front of the wall. So I'm considering an ultra short throw projector that's compact and easy to move.

We'll mainly use it for movies/shows at night with blackout curtains, and our budget is around $300-500 AUD. I'm interested in both new (local and overseas) and secondhand projectors. There are plenty of listings on Facebook Marketplace, but I'm a bit skeptical of them.

But to be honest, I actually dont know what the options are and what is the best option laser vs bulb...to select for this price range. I would really appreciate advices on how to test projectors if im looking to buy them 2nd hand and just any advices in general.
