The cheapest option, of course, would be to keep the K20 for your Pentax lenses. But the K-x does offer advantages in terms of high-ISO IQ, AF performance and burst mode over the K20... plus it's substantially smaller, lighter and less expensive than the K7. Reduced size and weight is a very legitimate reason for having a second camera body and/or system around. It makes particular sense if your other camera is a Nikon D90. While it's not Nikon's biggest or heaviest DSLR, it's not what I'd call tiny or lightweight, either. If you're not satisfied with the K20, than I'd opt for the K-x over the K7 at this time... especially if you have ready access to a Nikon D90.
I just want Da21 + a bit smaller camera like K-x or k-7.
I'm satisfied with K20D sensor, so K-7 is good, but sometimes thats not enough, better to say the result is not good enough.
And it's dillema, cause I can use Nikon for such sutuations, but I can't use pentax glasses
