What Gravel Cleaner Should I Buy?

I haven't ever used or bought a gravel cleaner before, I am looking to buy one now (new fish owner!). Any particular recommendations or does it not really matter which one you use? I have a 27/28 litre tank, if that helps. Thank you

 

For small tank like that if you don't need one with water pipe adaptor then get from ebay generic chinese one for few bucks

 

You don't need a fancy one--they just speed up the process. I got a cheap top fin one from petsmart and used it for the first time the other day. Made things go much faster!

 

This. I love it!! And cheap.
