Just got the last DS2 from the Stockport branch of Jessops - £329. It has taken me a while to go for a Pentax DSLR but I can now use all the lenses, flashes and other bits that would not work with my Fuji 602Z
Results from the Fuji, 3MP, stand up pretty well against the 6MP of the Pentax camera. But even with the two supplementary lenses it is not as flexible as the DS2.

I think that the hype about the new generation of lenses is just about selling us more pieces of glass.
I have just upgraded to a DS2 and i have gone through the whole of my lens collection and found them all to be functioning well and producing good images,
The filters also seem to be operating well and the polarizing filters are giving good results at intensifying sky tones.
Early days as I have only owned the camera for three days but I am pleased with the results so far.
