From dictation.The link you gave is for an item on Amazon. It has a split antenna, which is a requirement for meeting all of the specifications for the newest Wi-Fi standard. The Amazon price is about $90.
One could shop around to see if there's a slightly lower price for the brand name item, or one could accept a Chinese knockoff that may not have all the features.
One of the things you might want is the support from the brand name company. When you buy one of the copycat items from China you lose your opportunity to have direct support with the company that made the item.
Now, having said that, the chipset used in the brand name device may very well be the same chipset being used in one of the look-alike or workalike items that come from the Far East.
On that same link I noticed that Amazon features a competitive item that is very popular at a fraction of the cost. It goes for less than $20, but has only one antenna and is not have an extension cable. This could be an issue when you want the greatest possible range and highest bandwidth.
Now having said that, notice that this set low-cost item also is a dual band device and thus can overcome some of the interference problems found in older devices. Even so, the vice has to be mounted on the back of your desktop and may not be in the best position for optimum performance. My personal experience with this type of adapter has been positive. Only in a few cases have a found it necessary to make connections with the distant router. And when I did make a connection with the distant router I had to use a dual antenna device and the data speed was not very good.
The new 802.11 AC standard does not really guarantee you will have better performance than some of the older standards. It depends much on the environment and many other factors that cannot be changed by simply using a better Wi-Fi standard.
I would think that if one is willing to give up on the dual antennas and the ability to position the device for the best reception, the low cost item would be satisfactory. But that is my opinion. Here is the link that Amazon gives for the lower cost device that has most of the features you want.

EDIT: I just found this web site:
http://anewkodi.com/They offer a dual band adapter like the one in the Amazon link. But it is on sale for $10. I wonder if it is the same Amazon offers?
Sorry, it is not the same. But nice to know ANEWKODI has a web site.
