Just dropped from £118 last night to £95.37 delivered.
I actually managed to buy this from eBay last week as I was monitoring the price and although it seems expense for a wireless mouse/keyboard combi, it's a fantastic set with advanced features.
The Darkfield Laser mouse tracks on any surface and has handy shortcut buttons, the keyboard keys illuminate like a laptop keyboard when it senses your hands over the keys and is a dream to type on with a 10 metre wireless range.
Amazon reviews rate this 4/5 but many unflattering comments relate to the Logitech software which is downloadable to program the custom shortcut keys (which I've not tried, it works straight out the box).
The keyboard and mouse are both rechargeable via USB and it also comes with Logitech's Unifying Receiver, a tiny wireless USB dongle to connect up to 6 compatible Logitech devices.
Bearing in mind the keyboard (K800) is £82 and the mouse is £40 via Amazon, it's not bad. Hope it helps someone out.
