I bought a 28mm f/2.8 from Craigslist today. It's $260 on Amazon/B&H. I got it for $150. It's not as sharp as my nifty 50, and (clearly) the aperture isn't as wide.
I'll have to play with it more to test it further. While taking outdoor shots, it's not very sharp, and there's Chromatic aberration in bright light.
For $150, it's not too bad of a price if it doesn't work out. I like the wideness of it. It's more like a 50mm on my 450D cropped sensor.
28 x 1.6 = 44.8mm
50 x 1.6 = 80mm

Here's a comic I found that's hilarious and so true:
