Need help choosing a monitor

I'm looking for a monitor for about $250 or less. I will be using it as a computer monitor for gaming and video editing for the next few months. I will be moving into a new apartment in a few months with my friend and will have a gaming setup in the living room. This monitor would then move to my personal room and be used for the same thing, but will also be used as a TV for either my old PS3 or a Playstation TV/some other type of "micro-console."

I have done some research and found the ASUS PA248Q. It's a little out of my price range at $290. So, would it be better to get a used one from Amazon for $250 or look into cheaper alternatives? There are a couple Dells I found that would make a great monitor but I will eventually need the HDMI input that they lack.

I also looked into the Playstation 3D Display because it has an HDMI input, but it has very mixed reviews. Plus, I could only really afford a refurbished one (which I'm not super sure about because of all the problems). Also, I don't plan on using 3D, but the built in speakers would make it nice so I wouldn't have to get speakers until I wanted to invest in high quality ones.

I can wait a couple months and afford something better and more expensive, too. After all, I don't NEED it right now.

With all that said, do you guys have an opinion on what I should do or have recommendations for other monitors in my price range?

Writing this out makes me just want to wait so I can afford the ASUS or something nicer though lol. Anyway, Thank you. I really appreciate any advice.
