Wow! So many responses, look at what iv started! Haha
I did end up getting the Aqueon but bought a metal adapter with it as well (which hasnt arrived yet!)
I used it for the first time the other day and everyone is still happy

Yay I was so worried as id never put the water in without putting the dechlorinating it first. But i made sure to put some in before during and after and everything went fine. So much easier than buckets. I might try and use the excess water for watering the plants. Just havent figured that part out yet. Also, if you turn the tap on at first to start the vacum then turn off the tap, then the siphon still works albeit at a much slower rate! But then not loads of water is being wasted

You should try it...
