Actually, this thread helps answer a question that's been on my mind, which is do I replace the DS I have with the K10 or go ahead and put my money into getting a couple of lenses that I want while waiting for the price of the K20 to drop. If the K20 isn't that much better (and I really don't need 14mp, anyhow), then I'll see about getting a K10. Assuming I go the K10 route, I'll probably get one of the lenses (21/3.2) before I tackle saving up for the K10 body and then a dedicated macro lens. Other than an occasional LBA splurge, that should pretty much complete my kit.
I figure that by the time Pentax comes out with the next generation of bodies, I should be in a better position to plunk down more $$$ for a body (unless I decide to bite the bullet and get the 31--that's the LBA talking).
