Clearance deal on the Ctek CT5, note this isn't the normal MXS line, although I am unsure of the difference but seems to be optimised for start stop vehicles. Currently half or less than the price from elsewhere that I have seen. Was available at a number of my nearby stores for click and collect when I ordered mine.
edit, a bit further research leads me to think that the CT5 is a basically a user simplified version of the MXS ie it doesn't have as many user options but is designed as more of a plug and play option.
