I have a Davis VP plus with the solar and UV. I have the serial data logger with a keyspan serial/usb adapter. Originally went with a cheaper usb/serail adaptor but was getting lots of serial errors. The Keyspan is expensive (around $40) but well worth the money. My serial line is just phone wire of around 50'; love having such a long connection from the console to the computer. I use WeatherLink for modifying the console settings with VMWare; lot easier than messing with the console. Still downloading to the WeatherLink software though.
