Stumbled across this while looking for the cheapest unit i could find that was V3.1s (lots of 2.0 or 2.1 available cheaper).
This is also the nicer aluminium chassis version.
Couldnt find it for this price when i searched on Aliexpress but clicked on an old link from another forum when i was doing research and it took me straight here, surprised how much cheaper this is versus older models from all other sellers. Get one while you can.
Flash sale ended yesterday but using a new link you can still get it for the same price.
Coupon TECH4 might work at 5pm. It's not listed as a Tech Mania item so it likely won't.
