I have a few of the cable mountain cables, they seem nice enough for a few quid. For an extra quid or two they look and feel nicer and seem you may be able to plug/unplug them a bit more than some of the real cheapo ones I have. I wouldn't pay more than that though.
Is there any difference between one of these smarter cables and a cheapo one?
