Prinsu is the cream of the crop for a roof rack but you pay for it.
After that Yakima and Thule are two big brands that makes quality gear, but you pay for the brand name. These will be 200-400, but lean towards the high end of that range.
Finally, there are baskets under 200. I would only look at these if you can find 3rd party reviews or it has a sufficient number of reviews on something like Amazon. I bought this cheap cargo box from Amazon. It works fine, especially for the price, but it was difficult to put together, I had to replace the little screws it came with, and fill the places it connected to itself with silicon and wrap that in tape. For less than 1/4 the price of some high end cargo boxes, I'm pleased with it but since people might want something fancier.
If I found a good deal on a nice cargo basket I would be tempted, but only because it looks better and might be quieter. I don't think a higher end basket would actually hold my gear better.
It doesn't look like you have crossbars on Jadis, so remember to factor that into your price of a cargo basket. The prinsu rack linked above does not require cross bars.
It’s this one. Mine came with a tiny maxxhaul logo off to the side, not the big MF pictured
I got this basket off Amazon. You will need the Volkswagen cross bar kit.
I like this because you can put your stuff in a plastic tote and ratchet strap it down.

I have this from Harbor Freight. You can also get it from Amazon. I like the sleek lower profile on it 👍
