In reply to TattyJJ:
Ropes are a disposable wear item. I'd happily buy one from a mate/acquaintance if it was merely surplus to requirements, not their colour etc. I wouldn't buy one 'part used' from a stranger, it's false economy and there's an element of pointless risk.
30m ropes are cheap and plenty good enough for getting started cragging in a lot of places. If you're going to be going somewhere bigger or more serious requiring longer ropes to open up access end escape then consider getting one half rope and a 30m full rope. That's a very flexible combination that won't break the bank. Use the 30 as much as you can, you'll make mistakes as you learn and it'll hurt less when you damage it.
