Definitely have a go at repairing and cleaning them first. I had the same analogue stick drift issue with my ps4 controller and managed to sort it out myself following a youtube tutorial.I saw a Nacon Revolution for R1800 at games4u was gonna get that
so i must try and fix these ones hey
I think I can manage that ill give it a bash
I have to agree though that it seems they "don't make 'em like they used to". I had PS1 and Xbox 360 controllers that outlived the consoles themselves without any issues but my PS4 controller started palying up after about 2 years.
