I can't help with a recomendation 
but there have been a couple of attempts with wireless and they all seem to say the same thing - it doesn't work for an always on system. 
 
Wireless seems to hold together for about 24 hours and then fail for no reason.  If you disable and re-enable the device (or reboot the computer) you get another 24hours, but it's not a good solution.  That said, an integrated system may hold better than plug in devices. :shrug:
