Have a Panasonic shaver like this and its excellent and has been for years and was looking for one for my father for Xmas and noticed this one was 60% off which makes it a very nice deal.
Looking on price spy, it sometimes drops but its definitely at a low point
You can also get it for $149 - an extra $10 off if you sign up for a mailing list (any email will do) on the main page. Which makes even better.
Lowest price $158 March this year according to pricespy.
