Cheap enough to buy two and not so cheap it's poor quality. If you built cable like this from components it would cost about £2 for the cable and £5 for the two plugs - so you can see that a 90p version is cutting some big corners and you shouldn't expect much - but £3-4 sounds about right for a budget cable and thois one seems to be well made. If you want a super one that lasts for years then you'll need to shell out £10 or more. As a guitar teacher I see students with cheap cables all the time - they really don't last long and the cheapest will compromise the signal path and sound you get. So, as with most things, you pretty much get what you pay for. However, you can buy two of these for less than the price of a really good cable.
