Vinyl records (Braintree CM7)

Looking for 12 inch vinyl records to start a new collection. Pretty much anything from the 60s or 70s would be great. Doesn't have to be in pristine condition or collectors items. I've just bought myself a very good value record player and currently have no records to play on it. Happy to collect from anywhere close to Braintree or if you can wait a tiny bit longer I can collect from Colchester also.
