Paul, you are correct. Jessops on Line have them for £6.99. 2-4 weeks delivery which makes me think that they come from the USA. Yet no search brought up this supplier.
I did however want some other items from Adorama that cost half the cost over there and included the Rocket Air in the bundle.
Oh yes do want a bald Persian cat. Blew a fleck of dust off her and got more than I bargined for!!
