Sorry Scunner, didn't mean to cause offence, certainly didn't mean to be rude.
I was working on the assumption that if there is a big market for a product, which it is there, maybe the price would be lower. What Stoop said about the couple who would be dead before they had a chance to reap the benefits, reflects the high costs companies are charging.
I can see the point now, about a different kind of panel for each country usage.
Thanks for your replies, sorry again to cause offence.
