Maybe not cheapest all time, but cheapest right now. I paid $369 for one about 3 months ago.
I own one I use on my work laptop for work from home duties. Good monitor. I haven't done any gaming on it, but 4k/60 should look awesome.
And for the obligatory "eh it's not 144hz", you're right. It's not a competitive FPS gamer monitor. Display type isn't explicitly stated, but the QA says VA panel.

In my experience... don't pay extra for faster shipping from Newegg.

I think the sale ends Wednesday.
I will say my main gripes are kind of minor. The mini-joystick on the back you use for the OSD is annoying. The speakers are terrible (shocker) but you don't have to use them. Last I would suggest turning OFF "AUTO SOURCE" in the OSD setup to avoid headaches with computers that like to put the display to sleep (ie - my laptop)
AMA I will try to answer.
