I've got a Davis one, Vantage Vue model with the computer interface. I did have a bunnings one but the anemometer blew it self to bits after a while and then the rest of it pretty much fell apart not long after, it did did last close to 2 years though.
With the Davis one (and the bunnings one) the rain gauge gets tied up by spiders that stop the tipping spoon from tipping, so unless your cleaning and spraying it once a week forget the rain gauge.
The vantage Vue doesn't do the UV readings, I think the next model Vantage Pro (? ) does though.
The computer interface is essential if you want to check on what has happened while you weren't watching, you can also put your data online but that looked a bit to technikal to me.

The only other thing is if you buy one from ebay from outside Australia they work on a different frequency to the approved one here. Mine is imported and works just fine and does not interfere with my phone at all. If your neighbor has a head unit you can just buy the inside console and read his data, but you need to know if his AU spec or rest of world spec.( the head unit can be up to 300m away)
