Cheapest I've seen for a while. normal price is £57. An offer a few months ago was a bit cheaper but had a ridiculously long lead time. This offer is £35.21 with delivery in 3 days. Other makes such as Philips and Oral B have really bad reviews for reliability and performance but relatively, this Panasonic system seems to come out pretty well in the Amazon reviews.
