The wind datalogger is from APRS.
You can purchase it through APRS in the US directly : http://www.aprsworld.com/wind2/ or through us as a dealer for them, same pricing. We have the basic datalogger kit in stock. The quality is great, so far it has been a very reliable datalogger. The solar panel, cable, connector and casing can be purchased locally saving you on shipping. Shoot me an e-mail.
