If you're looking to spend around £150, you can get the WS2300, which has a
serial port pc connection. It measures all the normal weather variables,
and has indoor sensors for temp and humidity. It comes with software so
current conditions can be sent to your site. Theres an example of it at my
site www.dudleyweather.pwp.blueyonder.co.uk

This is the model
