This is the new shape 'Lite' Dualit, more closely resembling the 'Classic'. It's not a huge reduction from the standard price, but a good price anyway. It has very wide slots, and the bagel function to toast on one side. This is just what I've been looking for, not wanting to spend near £200 on the classic, but not liking the long shape of the older 'Lite' 4-Slice. The 5% voucher code is displayed on the page - SDAKW5, it states this expired 9/12/09 but worked when I tried it today.
I hope it's of some use to other HUKD'ers.
