These are back in-stock. Not the cheapest but still sell out quickly.
Only just got it home and haven't set it up yet.
New Firmware became available on 17/6/22. Version: F06
It's a stripped down version of the LG C1 48" which has been discounted as low as $1615 but stock is getting scarce.
@SickDmith: All assembled and holding great.
One thing to note if you do get the same arm is to adjust the counterbalance weight of the gas arm, I had to do maybe 20 full turns anticlockwise of the adjustment hex bolt. The arm will be up all the way when there's no monitor weighing it down but when the weight of the monitor sits on it, it will stay wherever you put it.
I put the feet on the FO48U first, then put the vesa adapter on, then you lift it up and lock it into the arm. If you haven't adjusted the weight correctly then it will sink to the desk and you'll have to turn the adjustment bolt counterclockwise more.
