I seem to recall that Sigma make a 20mm f1.8 lens. Not sure it's so great wide-open though, from reviews.
I have the Sigma 20/1.8. My impression is that it is sharper in the edges wide open than the 30/1.4. The 20mm is a nice lence that I'm very happy with. In APSC 20mm is close to the old classical 28mm wide angles, which suits me well for low light street shooting, in door conferences/meetings etc, and it also does well for landscapes.

Otherwise, the DA21ltd (if it is fast enough for you), and the A or FA20/2.8 have good reputations, and of course the great FA*24/2.

Avoid Sigma 30 if your camera doesn't allow AF adjustment. Use only with higher end cameras (k7, k5) which have strong AF motor. It has loads of glass to move around.

Buy only new, only if possible to exchange or return. Make sure warranty actually works in your country. Test extensively after purchase.

Corners are perfectly fine, unless you have very specific needs.

With the requirements you have, there is not much more besides the sigma, 24/2 and 31/1.8. Another option would be dedicated film/full frame camera specifically for this task.

I use Pentax A 28/2, and I love it. It is hard to find but it is perfect little lens, sharp wide open. Bokeh is very pleasant, contrast and colors are fine, build quality is superb, on par with Limiteds (I actually think it is better than limiteds).

I really, really want them to reissue this lens as a DA ltd. It would be the FA 43 for a crop sensor. Obviously, some would prefer the 43, because compromises are made in the 20s, but for a lot of us, the convenience of digital and the FOV of a 28 would be just... perfect.

I'd eve buy it as a 28mm f2.4 LTD... as long as it was a ltd...

Second the FA*24, fantastic lens.

Although I almost bought the 30/1.4, which looks great and would be better for subject isolation.

The 30mm f/1.4 ozzes with 3D effect, more so than alot of the Limited's.
Extremely soft wide open? Look up the page
My experience differs. Maybe sample variation? Most of what I've seen is from an Olympus mount, but I've seen some Pentax, and to me it lacks the pixie dust.

And yeah, both samples I've seen (on both mounts) were softer than, say, a FA50 f1,4 wide open.

I don't mean to trash the lens, I'm relating my experience.

Tough call. The Sigma 30 f1,4 or 20 f something come to mind, though their IQ is nowhere near the Limiteds. The 3D effect won't be there, if you don't find it with the 16-50. Both those primes are also extremely soft wide open.
What a load of BS.

Fa*24

I've got the FA*24 (f.2.0) and i just love that on my K-X as a walkaround option. Replaced my DA*16-50 for it and didn't regret that discission!

Good luck in your search!

The FA*24 is another excellent lens choice but can be hard too find.

Quick check and they are selling for US$600-700 over here

Think I'd stick to a MF Zeiss Distagon (24 or 28) for much less than that !

Another vote for the Sigma 30/1.4. I had a few reservations before I bought it because of the criticism it gets from some people (who probably don't own it and are going by other reports - which I find have exaggerated the soft borders issue).
What soft corners? - That's exactly what I was wondering about as well. I don't have Sigma 30/1.4 but have seen some photos taken with it in Yosemite....of course stopped down to 6.7 and 8.0 or so.....those photos were full size raws, so i downloaded them, inspected and couldn't see any soft corners whatsoever. I reckon that my FA31 might get more detail out of the corners, but those Sigma shots didn't look soft in corners at all.

I don't understand this talk of soft corners. Who is staring intently at the corner of your photo?

I would argue that if the cheaper lens has soft corners, please show me the cheaper lens! Soft corners are often equated with a 3-D feel, anyway .
