Hi David
I have the TFA Nexus, and I believe the Sinus is nearly the same, except the Nexus has solar powered anemometer. It's also know as Irox and Honeywell TE923...
My station is about 2,5 years old, and I'm very satisfied with it. In the start I had some problems with sensor dropouts, but after buying a new quality usb cable, and rearrangeing the sensors, I had no trouble for over one year now. Also I've modified the rain gauge to 0,2mm, and build a solar in a jar sensor. Everything working smooth under WD

So I highly recommend it, and a good budget station!
You could also find try search the forums - there's more threats about this station. Also I've seen a guy modified the antenna....
