My first DSLR was a Kx so I don't have any experience with the previous generation Pentax DSLR's. I imagine though, when coming to the K5 from a 10D, the biggest upgrade you'd notice in your images is the ISO performance. It really increases the options/possibilities for low-light photography (the unprocessed pumpkin-patch shot above is at ISO 800 with no added noise reduction). You're able to increase the shutter and/or narrow the aperture at virtually no "cost" to image quality (to a point).
The quiet shutter and 7 fps is pretty amazing too. Oh yeah, and TAv mode... The features go on and on. If it doesn't hurt your pocketbook too much, I say take the leap!

I can't say enough about the DA40. I've never shot with the FA43, so can't persuade you one way or the other between the two, but the DA40 is almost too good to be true. If you've got the Kx, Kr or K5, it's unbeatable for the portability alone. There are times I bring out my K5 + DA40 when I know I wouldn't otherwise bring out my gear. It's still not necessarily "pocketable", but close to it and very discreet for travel, street shooting, etc.
The relatively slow aperture for a fixed focal in that range is no problem with the ISO performance nowadays - and it's superb straight from f2.8 (sharp corner to corner).
Just my 2 cents.
