Please be wary of anything but the two links previously mentioned by another user in this thread. These units are small, cheap and relatively easy to knock off. There are a lot of less then reputable units out there for purchase. Be patient and use a known good seller, for your benefit.
go figure....the txco kit with antennas is out of stock and the dongle alone is out of stock. can anyone suggest any stateside places selling the dongle(s)?
