Topic: Printing Record Sleeves

How is everyone going about making up sleeves at the moment?
Seen this guy do some really good screen printing jobs recently:

At the moment I'm thinking about possibly doing one of those super basic 'folded over piece of paper' sleeves - does anyone have any tips on cheap places in London that have a good service for something like that (high res scanning, printing double sided, odd size/cutting on different colours paper, etc.)?
