DA 21mm Ltd (or the 15)

Looking for a 21mm Ltd if someone has one for sale. I'm also looking at the 15 as another possibility.
I've been looking at both of these and haven't come to a full decision on which one, but I'm leaning more towards the 21.
I think I'd prefer the SMC version slightly, but it doesn't matter much. I'll see what people have.

Cheers

Are you looking for an HD or SMC version or does it matter to you

HD vs. SMC Pentax Limited Primes
Introduction

At Photokina 2012, Pentax announced a brand new lens coating which they named the "HD Coating". This coating is slowly starting to replace the conventional "Super Multi Coating" (SMC) on high-end Pentax glass. According to Pentax, the new HD coating greatly reduces reflectance without making any sacrifices in terms of durability. This kind of coating isn't new to the industry, however: Pentax digital medium format lenses have been treated with a slightly less durable variant called Aero Bright coating ever since their debut, and other manufacturers have been using "nano" coatings on their premium lenses for several years.

The modern SMC coating that DA lenses have been using for about a decade now isn't the same as the SMC coating that Pentax originally launched in the 1970's. In fact, most DA lenses have been said to have a "ghostless" coating, so while we don't expect the difference between SMC and HD coating to be be a game-changer, it should certainly still be easy to observe. . . .

Thanks, what else will you be selling (I really shouldn't ask as one lens at a time should be good, but LBA is a tough master...)?

One thing to note is the HD lenses have curved aperture blades where the SMC lenses have straight ones,

While this is generally a good thing for bokeh, it ruins the amazing stopped down star burst effect the SMC 15mm had with lights. The straight blades give you a sharp, clear, straight ray, the curved blades spread it out and make it less distinct. In thumbnails it's not an obvious difference, but at printable sizes, it's clear.
