Please help buying my first DSLR! :)

Right now it seems to me that it's like this:

Pentaxes:
+ great WR on house and cheap WR lenses
+ good sensor, IQ, OK buffer etc
- slow AF for action (unsure how much better the K-5II/K-30 are over the K-5, if the K-5 can do the job)

Nikons:
+ good sensor, IQ, AF
- poor buffer
- WR lenses are very expensive

Canons:
+ good buffer and AF
- WR lenses are very expensive
- poorer ISO, IQ, sensor

Sony:
Basically same as the Nikons
+ some panorama and stuff

I'm very partial towards the Pentaxes because of WR. I'm not primarily shooting sports/action I think, but I think it would be nice to have a camera able to do that too. (I'm ok with not all shots in a series being ok, but at least some keepers are nice).

If any of the others would have had a buffer good enough to handle 3 seconds, excellent sensor/IQ/ISO/WB, I guess I could have practiced the plastic-bag trick to cover the cameras instead in mild rain etc.
