Unfortunately I have seen failures reported for 901s through 905s.

Price is set by the idiots running the global financials, value of whatever currency you are using to buy with has been lowered by various schemes. I am assuming that the real cost of glass is the same.
SDM failure is a design flaw that due to Japanese psyche was never admitted to correctly and an awful lot of the reviews are of owners venting due to a real or imagined failure. This should have had a general recall but some spreadsheet with cost / brand value analysis indicated otherwise.
Character, this is harder to define, but from what I can gather, the DA* is a bit of a lottery from a optical QA point, some are stronger wide open than others, some reach peak sharpness at f/4 while others need f/8. Suffice to say that wide open, center will be sharp enough, stop it down and the rest of the frame catches up. Absolute sweet spot is dependent on your actual lens. I have seen some fantastic shots from this lens with great contrast, colours and sharpness throughout the aperture range. Suffice to say it is one of those lenses that you will need to learn and understand to gain best results but instead of GCSE level of learning, think Degree Thesis
On the other hand, the DA16-85 is overall more optically balanced from a performance point. It has the typical Pentax contrast, colours, better flare control and more stable resolution parameters across the frame. It will also focus faster which is a bit of a mute point as both these lenses are not really targeted for sports / action but again this is a usage parameter. There is one user on Flickr that put up some absolutely stunning landscape shots that had me about to hand over €800 so optically it will deliver top of line results. It is also lighter, will come with a warranty and will work very well with current Pentax DSLRs.
But...
It is like a DA Limited verses FA Limited argument (debate). DA is easier to use with more of its performance available more if the time, DA* is harder to use (assuming you get a reasonable copy) but it's highs are completely out of reach of the DA, get it in its sweet spot and it will give you a very 'prime' like look.
I'm picking the DA*, used and will budget for SDM failure. I might get lucky, I might not.
