Hello, Billy!
I am willing to add mu piece of info, and hope it will help... I had the very same dilemma as you are having just 2 weeks ago. K10D or E510? I was thinking about it day and night. reading countless reviews, forums, viewing samples. At last i bought Samsung GX-10 (which is rebadged K10D, exavtly the same camera, even made on the same fab, having just different-styled buttons). This is my first DSLR, and i tried it for these 2 weeks, so here i can say that, for a SLR-beginner as i am, seemed good or bad about it.
Ok first are the goodies
The build quality is excellent, and it feels perfect in the hand. It's rather heavy weight i see as a good thing actually. The optical viewfinder is comfortable, and rather large. The overall handling of the camera is logical and easy, nothing is hidden where you cannot expect it, all is in it's place. The image quality is great (NOTE! See below in what i did not like about this too), sharpness is enormous for 10MP cameras, much sharper then Nikon D80 and D200. The colors are (from my point fo view) are much better then on Canon DSLRs of this price range. Nikons and SONYs have the same colors, as they have the same sensor.
What I don't care for. This camera has to be tamed. I mean you cannot get it out of the box, charge the battery and take great pics. Actually if you'll do that, you'll be greatly diappointed, as was I. You have to tweak in-camera settings to match your view of a good image quality, and you have to learn how to use other modes, then P.
And now, what i did not like. First thing that bother me after having Panasonic FZ-30 (which has VERY good in-camera processor, doing many things for you) is that i have to tweak somehow (more or less) outdoors photoes before i can show them to someone. I am used to good out-of-the-camera pictures, with corrected shadows, etc. Pentax does nothing like that, so quite typically, if you have sky and a house on the same picture, the house will be darkened to leave the sky color natural, and you'll have to tweak shadows later in photoshop or other program. And the second thing, auto White Balance in this camera is not very good. If often makes wrong calcualtions, and requires corrections later.
Both things that I concider to be bad are not a issue if you are comfortable with shooting RAW files, as you have to anyway tweak them for colors, shadows and WB. I, however, am not yet adopted RAW shooting as my primary, maybe i will in time...
So, as a conclusion... K10D is great, even perhaps the best 10MP DSLR under $1000, even under $1700 or so, in terms of picture quality. However, think about post-processing MOST of the pictures, think are you ready for it or no. Olympus E-510 will give a little less quality in pictures and a little more noise, true, but it's out-of-the-camera pictures require little to no post-processing, which i see as it's main actual benefit.
Am I happy I've chosen Pentax system over Olympus? Well... Honestly, I am still not sure. But well, I already jumped in, so I hope I'll like it in the end lol
