In reply to samben6:
People climbed at Avon before cams were around. Whilst some would be desirable, it'd be wrong to think they're essential if you're just starting out.
You can get up a lot of things with a full set of rocks 1-9, doubled up on 1-6, quickdraws, a few four foot and eight foot slings, a few hexes (8 and 10 say, on rope) and, most important of all, a broddling stick. It's still a fair chunk of cash, which is why many of us started climbing with a mate and each bought a matching half of all of that.
Plus the knowledge on how to use it all safely, of course. That's on you, not me or anyone else.
