And for those that might be interested you can download Serif Drawplus for FREE from here: http://www.freeserifsoftware.com/default.asp
Although bear in mind the map was made using drawplus version 8 and the free download is version 4, so many of the features in the free version may not be present - particularly 'add, subtract and intersect' which allow you to combine shapes. Although having said that Serif products are much cheaper and IMO much more intuitive to use than the top end vector products like Illustrator and Corel Draw.
