Um, good enough to make my clients happy? Good enough to take photos I can show to potential clients that inspire them to hire me? Good enough to keep working?

I dare say I am missing NO shots using my Pentax cameras. I have been through thread after thread on other forums for wedding photographers where Nikon and Canon users are complaining about missing shots because autofocus locks—but focus is poor. Now I'm not knocking Canon or Nikon autofocus, either. Cameras work differently. You just need to know how to work with what you've got.
Alfisti, you're a good photographer and I respect your view here, which is different from mine and certainly has its own validity. But I think your criticism of the Pentax DSLRs here is mistaken, at least within the context of this thread, which is about wedding photography.
When I was shooting sports, I DID miss shots using my first Pentax DSLR cameras, because I was quickly changing my targets (I shot a LOT of volleyball, and would move constantly from right to left, from one player to another), light inside the school gyms where I was often shooting was almost always poor, and autofocus sometimes simply wouldn't keep up with me.
But a wedding is NOT a sporting event! Much of what happens at a wedding is 100% predictable, at least for an experienced wedding photographer. Whether it's before the ceremony in the bride's dressing room, or during the ceremony, or at the reception, I just can't think of a time in the last couple of years when I've had a problem with the autofocus on my K20D or my K10D. And I assume that the K-7 is not worse than those cameras.
I WILL say that I have a small problem with the bouquet toss. The problem isn't with focus, though. I position myself so that I'm at the apex of an equilateral triangle whose other vertices are the bride and the first single girls in the group who will try to catch the bouquet. I'm invariably shooting with flash at this point, can set the aperture to f/5.6 or smaller for good depth of field, focus on the bride, and I can whip from her to the group without worrying about focus. The problem I've had is with the flash recharging. If I have my battery pack with me, I can probably take two or three flash shots in very quick succession. But what I tend to do is ask the bride to "fake" the throw the first time—to start the toss, but simply not to let go of it. I can photograph that. The second time, she gets to throw it, and I am pointed at the person who catches the bouquet. Works for me.
I can't think of any other autofocus problems that I have. I would love to have 20K to spend on a couple new Nikon D3ses and half a dozen primes, to match the Pentax system I currently use. It is possible that in some situations—especially shooting in the church without flash—the better high-ISO performance of the D3 would make a difference. But I don't think it would make any difference to the focus of my photos.
Quote: Given that the two workhorse lenses (16-50 and 50-135) are notoriously slow to AF I just think it's not what this system is designed for at all.
One of the (many) reasons I shoot only with primes these days is that I find them easier and faster to work with. I simply don't THINK about zooming any more. It's simply not an issue for me.
So, if you ask the question, why shoot with Pentax when you could shoot with Nikon or Canon (which are presumably better), my answer would be that Nikon and Canon aren't better enough, in ways that matter to me and my clients, to inspire me to want to spend more money for them.
If I were starting from scratch now, if I had nothing invested in Pentax equipment, and if I were free to pick any system available, I'm not sure what I'd pick. I'm really not. Sony maybe. Maybe Nikon, because of the flash system. But I'd probably still look at Pentax carefully.
