Hi,
Thanks, I was able to look at the page then.
Well, as far as I can see, it's just a form with radios and images attached to it. That should not be a problem with custom item fields. then.
If you need the price to change based on what is selected in the fields, then it might require a small custom price override plugin to be build, but nothing complex. And actually, you might want to use a characteristic or an option for that selector so that the price can change automatically and keep custom fields for the rest.
