Thanks for the warm welcome everyone! I ended up ordering a K-30 in crystal blue (body only), should be here hopefully by Friday, can hardly wait! Yes, could have gotten a K-50 (used) for about the same price (new only slightly more), but the K-30's styling and metallic colors really do it for me.
I'm now looking into lenses from the usual pre-owned sources, as I'm on a budget.
So far I have on order a 28mm F2.8 and a 100mm F3.5 macro. I definitely want to get an 18-55mm WR for wet weather shooting (otherwise known as 'Not Summer' in the Seattle area most years), and am considering a 50mm F1.7. I also want a zoom with a 200-300mm reach, but that can wait for summer airshow season. There seem to be lots of options in that category when you discount the need for WR.
Cheers!
