Here's where subjectivity comes into play. I agree with Paul about more pictures and less text, I clicked the photos expecting them to enlarge for example.

However, as a customer, the 10 year guarantee would be important, maybe not the main feature, but still high on the list.

And those example sites? The first 2 are very old hat in design and the last one is a mess of animated glitz and template blocks.

Lastly. Please post your views when they've been asked for and not PM them. I, for one, learn how people react to different layouts from the comments.
