Andy, I'm glad that helped. As to the color and 3D stuff, have you seen what Nick Sonder is doing? I'm no expert but I think he, and you, have an edge by using color and perspective 3D. It may take some folks a little while to get used to it but the additional information you can give that way is a huge benefit.

In UK only option is to buy through a third party. I bought through Cabs-cad. Really nice people. No problems at all.
