average price for a polytunnel?

i was watching river cottage the other day (a few years out but not by that much) and i was wondering if they had gone above or under �£300?

I've just (today) finished building staging in one I bought from the first link that Nixon has posted.
Cost �£370 for a 15' x 8' delivered. Delivery to you will be free I think - cost me �£15. Add to that �£20 for paving for a path in it and about �£25 for staging.
