Capt 69 was £8 a month membership, don't know if it's still the same. A relatively small fee but it still seems enough to weed out the nonsense you get on AW and sometimes on Pnet.
I always used to join before a visit to London. It's so London orientated that it isn't worth it unless you punt there.
I remember once I was about to book a girl from an agency simply because I liked the look of her - I was naive in those days!
- but then saw she had a couple of poor reports on C69, so the £8 saved me £150.
I don't bother with it nowdays because I have a few contacts and regulars.
