While there's newer monitors coming out right now, if you're dead set on VA panels and want good value, this is it right now and is at its historically lowest price. Delivery is $15, or free with eBay Plus.
Biggest trade off on VA is the slow response times of darker colours, in this case most typically noticeable at 60-90 Hz when Freesync is engaged. This monitor tries to move around that by offering a couple of backlight strobe modes (similar to black frame insertion techniques) in lieu of traditional overdrive settings, but this also forces a fixed refresh rate.
You'll have to check reviews (like this, though keep in mind the 27" model doesn't have those PWM issues) to get a better idea if this monitor suits your use case, but if you're happy with the trade offs, colour and contrast wise this is fantastic for a gaming monitor for the price.

EDIT:
Apparently some people need this PSA: Freesync monitors work fine via DisplayPort (not HDMI, yet) with Freesync mode enabled on GTX 10 series cards and higher thanks to a driver update from NVIDIA:

Just change the setting in the NVIDIA control panel.
