I finished installing my second weather station today. Its a OS WMR968 that I bought of ebay from America. Cost £150. Its exactly the same as the WMR928NX that is available over here but obviously you don't get the support if you buy from America. The WMR928 costs over £300 here. I previously had a La Crosse WS3600 and had many problems with it so I wouldn't recommend that. I don't know what the WS2500 is like so can't comment on it. The Matrix II that dazza provided a link to is a rebadged La Crosse model. What you've got to ask yourself, is what readings you wish to measure and then find a station that gives you the most for the cost. Generally the order for quality of the weather station goes Davis, Oregon Scientific, La Crosse. Although that isn't true for every model. A La Crosse will give you the most bang for your money and are great for beginners in weather stations. I hope that helps.
