Adorama has one used lens listed on Amazon with 6mo warranty for great price:

Amazon.com: Buying Choices: Pentax 21mm F/3.2 AL Limited Lens for Pentax Digital SLR Cameras

(might be a type but if someone needs it (grab it before it's too late, I think it's a great price from reputable seller)

It is not necessarily subotimal. But it IS poorly matched to that particular camera.

Why?
Is it CA? Handling? Something else?
I am not trying to be snarky.

No, I am not refering to the optical qualities of this lens. I mean that the manufacturing tolerances of the lens and camera are poorly matched, resulting in a focus bias that cannot apparently be corrected even with the fine-tuning of the camera body. It would probably require factory adjustments of both the camera and lens, which could lead to different bias for the rest of the owner's lenses.

BH photo still has the DA 21 SMC limited for $489 with free shipping -- these are new. I got one. Very nice lens for street photography - essentially near equivalent to a 35mm on FF.

For those interested, lens is being returned. I decided it just wasn't worth the hassle of entering debug mode everytime I want to use it....there are other copies available. SO if you're interested....it will be back at Adorama sometime next week.
