Well ... I just bought two xBox One controllers with USB cable... it was $27 each ("used", but 12m warranty) so I assume that it's nice price 
Wife will kill me because in 1 week I bought 2 wiimotes, motion pluses, nunchucks, infrared bar, speedlink charge station with batteries and gamecube AC to power it...
Hope it will work
I'm not feeling that buying 4x Wiimote is good investment if ony 4-player games that are interesting me are Brawl and Mario kart - with those games two persons may be comfortable to play with xBox controllers IMO.
There is also Tatsunoko Vs Capcom (two players - better to play on normal gamepads... or any PC substitute game for this one), and lot of Steam gamepad ready games.
I assume, that I'll setup Steam Big Picture as default windows startup/shell, and have Windows as my game console instead of PS4/xBox (I'll tell my wife that buying this stuff which I bought is lot cheaper than console
)
