I've got an upcoming visit to the West Island, and I noticed that K-70s are under $900 there allowing for exchange rate.
I had been thinking of going for a KP, but looking at a thread on here,
KP vs K-70 - to KP or not to KP, that is the question - PentaxForums.com
The K-70 is actually a pretty decent camera in its own right, and quite a bit cheaper than the KP.
While I'd dearly like a KP, it seems like the K-70 is still a decent upgrade from the K-50 (which is still working fine - just it's starting to limit some of the photography I want to do.)
The balance that I'd otherwise have spent on a KP, I can put towards a lens upgrade.
I really want a lens that's sharp and reasonably fast in the 70-200mm range, but these don't seem to come cheap, so spending less on a body leaves more for a lens.
The difference in price between here and across the ditch for the K-70 looks to be about $300, however photowarehouse here throw in a kit 18-55 for effectively $37 more which I don't need, but in AU, with the kit lens, it's actually more expensive than here.
I don't know what the resale value of a kit 18-55 is, but that might narrow the gap in prices, and presumably photowarehouse have a NZ warranty.
