I am a Wordpress addict now - all new clients of mine are being pushed in that direction for it's easy management even by a new user. I normally set everything up for them and then give a little tutorial on what they need to do to update pages, add more images to a gallery etc.

My Sketchpad site is http://craigssketchpad.co.uk/ which uses a Wordpress system.
Also http://craigjohn.co.uk/ & http://graphicbasics.co.uk are too.

My business site isn't a Wordpress site but it has all the pricing info - http://www.cjproductions.co.uk/ but I'd recommend looking elsewhere if you're in a hurry - I've got several large projects that need finishing first (no maps unfortunately, but loads of illustrations and page layouts).
