Lens makers have known how to make good lenses in the OP's 28-35mm range for many years now, especially at the 35mm length. If you pick any of the "good name" 35s from about 1960 or newer (maybe even earlier), or a 28 from maybe 1980 or newer, you're probably going to get a fine lens.
I think SLR wides made some real optical progress in the 1980s. 35mm isn't that wide.
As you move toward a lens that was marketed more for cheap price, your chances of a less than fine lens increase.
