"Best" zigbee dongle?

I've been lurking this sub for several months, and I'm eager to try out homeassistant for myself very soon. I'm currently assembling the hardware needed, but a bit hesitant on which dongle I should buy for zigbee connections. My brother is in the US over the holidays and I'm taking advantage of that by ordering things off of Amazon for him to bring back, so I'm preferably looking for options that are available on Amazon with prime shipping. However I'm open to all suggestions, any feedback appreciated!
