High Coverage And Quality Wi-Fi USB Adapter

[Borisyo]

I have seen usb MIMO wi-fi adapter but nothing was mentioned about coverage. I saw another adapter without MIMO but with high coverage (x4 range, don't know how far this is). There is Edimax, Cisco / Linksys, Hawkin...

I need high coverage and high quality adapter. What usb adapter would you recommend?

What do you mean by quality? The quality and build of the hardware? The functionality and flexibility of the firmware? Most will have quite similar coverage unless you are trying to get one with flexible firmware that can be tweaked for cracking-type activities.
