When I started purchasing things on Thomann, I discovered The Sssnake cables and they became my favorite brand for pre-made cables. They are cheap, well made, you get what you pay for (and more, really).
Cable itself is 5m long, cca 0,5 cm thick, it has screw-on metal DIN plugs (5 pin) that could be detached in case you damage the cable. I use it to connect footcontroler to audio card, I have no problems with it, seems reliable - it even managed to pass The Test - e.g. survive continuous drunken stomping of my fellow bandmate on it - and believe me - some other cables did not live long enough to tell the story :-)
