Actually I like the black standard ones as well, but this is maybe the ONLY chance ever to get a very unique colored DSLR, I can always go back to use the black ones later on.
So I ordered one of the various color variations x_X
Furthermore they don't say anything about not being able to return in on the Pentax site and also not on the shop site where I eventually ordered it from. They only say that you'll have to wait for about 2 weeks. So let's hope the best ^^;
