Nayr, definitely worth paying a little more and getting the eheim liberty, ive had a few hobs and the eheim is 10 x better than the APS ones or ebay £10 ones... pretty sure those 2 are the same filter anyway. The eheim ones have adjustable flow, are still cheap, give good flow around the tank and have way more space for media.
