Back the original question:
there must be something wrong with the Pentax *istD/DS/DS2/DL/DL2 line.
Recently i did a few Ebay searches, as i am looking for a third Pentax body, to be used for "macro hunting", and compatible with "true" TTL-flash (not P-TTL!).
The D/DS/DS2 models would allow me to use a multi-flash setup, with a dedicated real-time sensor, as i did with my LX.
I was surprised by the number of malfunctioning/repair/parts-only cameras i found on sale!
I didn't take the time to read the text of the auctions, so i can't remember which *istD variants were affected.
I have nothing against Pentax, BTW. Quite the contrary, in fact!
I own all the best analog bodies, from the K2 to the 6x7, and most (read: very close to "all" ) of their best manual focus lenses. Late 35mm AF bodies (like the Z-1), and early digital ones (K10D, K200D) are still working without a single hiccup.
I hope i made it clear enough... if i didn't, i can add that i loathe Canon (the F1 was a camera!), and that, while i appreciate Nikon (and i'd probably buy one, if i were a newcomer), I'm not too keen in following the crowds, at this point of my life.

That is: I shoot 8x10", but i don't own a Deardorff, even if a Century Universal ain't so cheaper.

Whatever, now that i'm cleansed from any suspect of being a Canikon follower

i can't deny that the number of failures of *ist digital bodies are unusually high.
There must be some weak spot.
Maybe the failures show up only under some circumstances, but i can't elaborate, as i don't own one, and i haven't done any serious search about the subject.
I am personally interested though, as i want to buy one

Please chime in if you have some infos.
On a more general level, i can say that NO Pentax cameras ever failed on me, weather sealed or not, and that the two digital bodies are still working perfectly, even if they were purchased second-hand (and one of them had seen a lot of use).
I have the feeling that the weakest link in contemporary cameras is the lens.
At the root there is the big unsolved problem of electronic equipments (and electric cars): batteries!
Until there is a breakthrough in that technology, battery juice must be spared, so lenses must offer very low "drag" to the AF motor (and power-zoom).
On top of that, kit lenses must be economical, despite the fact that electronics are getting inside the objectives.
The result is under everybody's eyes: some lenses are so badly built that it's a marvel they don't fall apart.
At least Pentax makes a couple of cheap WR lenses. Poorly made as other makes, but at least sand and mist won't easily find their way inside the optic!
