If anyone in UK is looking for a 16GB HC card for a Camcorder or still camera with video capture facility, have a look here :
http://www.7dayshop.com/catalog/product_info.php?cPath=777_6&products_id=110291 It's a Class 10 card so is capable of recording at the highest quality. Furthermore, the price is great £16 !! Because the company is located in the Channel Islands, there is no VAT on items priced below £18.
The card will not work in your KN7000 or some other devices, since it is designed to work with devices suitable for HC cards, so check your device specification......
I have used this particular 'brand' (Transcend)of SD card in the past and had no problems.
