Well, it was only that price when you posted your message. Now it's fifty three pounds! I bought the Complete BG MS/S1-3 and sold my old MS, S1 and S2 on ebay, meant I only paid thirteen pounds for series 3. It also takes up less space which is always useful. I have no idea why the Complete BG was ever as cheap as it was though, especially with S3 just out at only a bit less.
