K30 is the equivalent of the d5100/5200 (range wise, but better in some areas), and whilst lenses are the primary arbiter of what the sensor receives, better sensor utilisations are a welcome addition.
For me, the K30 is a no brainer in the current market - it's extremely well priced for the features it packs, and there's plenty of lenses to choose from by Pentax themselves, as well as the usual 3rd party brands.
What sort of budget are you realistically playing with?
I personally would go for the Pentax if only for the option of the 50-135The best lens I have ever owned.

Did you order from a Pro dealer? That gets you a 2 year warranty as opposed to standard 1 year from the likes of Amazon, etc.
