I found two options. Weathertech and Britpart. There are cheapos on ebay and amazon, but from what I heard they already failed when they tried to install them (do not fit).

Weathertech is $75, but only front.
Britpart is $70, front and rear.

Edit: I also found TF, $80 front and rear

So which one is recommended?

I ended up buying these and then trimmed the front edge off with a dremel tool; they then fit perfectly. And have been attached for over a year.

 

I got mine from Britpart. Had no issues other than having to use more tape when a bit failed

 

You guys are making me spend money.
I want these been thinking of getting some
The wind turbulence on these discos are terrible. If I have the front window open it’s so turbulent I have to crack the back window to smooth it out

 

I run all year, save for rain and snow, with the front sunroof open. In the summer it is all four windows and both sunroofs.

 

I went with the Britpart DA6071 delivered from lucky8. Easy to install, good fitment except for a small overlap at the front doors. Tinted visor material is 2mm thick, feels solid and absolutely no movement at highway speeds. Wind noise is significantly reduced, although not completely gone as expected. It came in original Britpart packaging with tag "made in Taiwan".

 

While the aircon in my Disco works just fine, I only use it enough to keep it working (once a month for 5 minutes) I find those visors to be a godsend on rainy days. I can also leave my windows open at the top while parked in all weather as unless it is blowing a gale, no rain gets in
