I'm glad I have seen this thread as in the same predicament. Seeing pics etc I think I may go down the K5IIs route.

The extra money is not a big issue, just wished I could get it with the 18-135 as a package!

I got the K5IIs and I am quite pleased with it. Just the 18-55 WR does a GREAT job. I can't wait to see what a "good" lens does on this camera. Unlike Canon, you don't have to spend a small fortune on a lens to get a decent picture out of their cameras.

Moire will be around as long as the pixels on the sensors are arraigned in grid like pattern. The only way to really get rid of it would be by randomly scattering the sensor pixels across the array. If they were arraigned more like silver halide crystals in film, then moire would be a thing that us old timers would be able to regale newbies with. FWIW, looking at my second K5 (K5 IIs), but I still think film has it all over digital photography.

BTW, weave structure predate imaging sensors by several millenia I blame the sensors for not being designed to take this into account. :-) Bad vignettes drive me nuts too.

I wonder if there is any difference in exposure under same light condition after removal of AA filter? In theory, AA-less sensor should get more light thus fast shutter speed. If it is true, it should be the biggest sell point for me, since I can keep either ISO lower or shutter speed higher under low light. Any hand-on experience?

Considering how thin Bayer AA filters are the difference in transmission would be less than 0.001 of a stop.

Incorrect - Moire is only a problem with Bayer array sensors, if you remove the Bayer Colour filter array - you end up with a monochrome sensor: which is immune to moire, but the individual pixels are still in a grid pattern.

Also the AA filter is not removed but replaced by a neutral filter. In the end it should make little to no difference.
In terms of noise the difference will be that you don't need to sharpen a camera without an AA filter so much then one with.

I see. Thanks.
For some reason, my impression was the AA filter caused 0.5-1.0 stops of light loss. Now I found this thread says that: AA filter removal - I'm gonna do it: Olympus SLR Talk Forum: Digital Photography Review
That sounds way too much. And I also read this, says <1/8 stop: VAF-Series Optical Anti-Aliasing Filters: FAQ
