I don't dislike the K-01; I own several of them, and bought my first one BEFORE the closeout prices. Having shot the K-01 for three years, I don't think it's a good match for what you are looking for, and buying the wrong camera because of a sale is usually a bad decision. I pretty much gave up participating in the K-01 forum because of people who bought the K-01 cheap and then wouldn't stop complaining because it wasn't the Sony or Fuji they wanted.
You say you want a compact body to shoot wide-angle with K-mount lenses. That's one of those "pick two" situations. No digital K-mount camera is compact compared to short-register MILCs and fixed-lens compacts. If you put a K-mount adapter on a compact APS-C MILC (Sony, Fuji, Samsung), you lose much of the compactness along with autofocus and auto aperture control (and possibly some IQ if it's a poorly made adapter). If you do the same with smaller sensor MILCs (Q, M43), your have the same problems, plus your wide-angle lens won't be as wide - you really need a native-mount WA lens.
For that matter, the only "compact" K-mount ultra-wide-angle lens is the DA 15 Ltd. None of the UWA zooms I've seen were small. Most of them are f/3.5 or slower, and the K-01's autofocus hunts a lot with slow lenses. Regarding slow operating, I can't find the exact quote I'm looking for, but it pretty much was: slow focusing, slow buffering, slow frames per second. It's not an action camera, which might not be a problem for you; it's also tricky to use outdoors in bright light because the screen can be hard to see. It works well with manual-focus primes, but that's generally for people who have plenty of time to set up a shot.
I would recommend shooting your K-30 exclusively in LiveView for a couple days, and see how well you can stand it before jumping on a K-01.
Oh, and regarding reviews of the K-S1: now that the prices are coming down, there will be more and better reviews. That's exactly what happened with the K-01.
