The K series do seem to be better regarded than the M, but I´m not sure how much of it is based on fact. The only K series I have is the 55mm 1.8, which is probably the most common. It´s M series equivalent would be the 50mm 1.7, which I also have. The K is slightly sharper wide open, but there´s little other difference apart from size & weight. It seems to me that the older the lens line the more mythical the qualities become, though this may be age or the classic build quality, which has decreased substantially through the years. Taks are highly regarded though many of them are not so good due to the poorer coatings, Ks a little less so even though many are essentially the same design as the Taks but with improved coatings. Ms are not so well regarded perhaps because they´re the most common.

For 67GBP you can get a new Yongnuo YN560 on Amazon:

It´s a dumb flash, so everything´s manual, but the build quality is superior to any of the old Pentax flashes I´ve seen, it´s powerful, full tilt & swivel and power is very adjustable. I´d recommend it.

The problem is that this is a company that employs sales assistants who don´t know what an aperture is.

I would go to Jessops for a look, or for a bargain, but not for advice.

I´d say that´s a fair assessment of it´s place in UK photography retailers.
