I searched it on ebay:
http://www.ebay.com/sch/i.html?_trksid=p2050601.m570.l1313.TR0.TRC0&_nkw=AP121U&_sacat=0&_from=R40
I noticed this seller:
http://www.ebay.com/itm/ALFA-Portable-Wireless-Router-AP121U-with-USB-Port-5dBi-Antenna-12V-DC-Jack-/370785953479?pt=LH_DefaultDomain_15&hash=item565490a6c7
But when I try serveral times to contact with all sellers that selling it.
no one respond to my massages im afraid to make the purchase and he will not send me the item.
If anyone already buy it from this seller and all was ok, please notice me.
and one more thing, it will work with EU plug adapter right?
