Good morning, Sage;
Finding a 17 mm or even a 20 mm prime WA lens in the Minolta Maxxum, AF, or "A" mount is going to be a challenge. I have the Minolta Maxxum 9 body, but the competition for lenses by the guys with the Sony Alpha digital cameras (which uses the same lens mount) means that finding used glass is not easy.
I do have the 17 mm, 20 mm, 24 mm, 28 mm, and the 35 mm Rectilinear WA lenses in the older Minolta SR/MC/MD manual focus mount. The widest lens that seems to be "normal" to use is the 24 mm. The 20 mm is a lens I need to be careful with when using. The strange effects you can get with the 20 mm must be carefully considered. Moving out that silly additional 3 mm down to the 17 mm relegates that lens to a "special purpose lens" category, even though it is still a "rectilinear" lens formula. The next lens down at 16 mm is not in this category; it is a "full frame fisheye lens," and is something that I use only for special effects. Poisson du Jour has given you some sage advice (sorry about that).
I have found the 24 mm lens to be adequate for photographing the interior of a room for my purposes.
I have not yet found a zoom lens in this range that I felt gave me the consistent performance of a prime lens at these focal lengths. At the same time, I also admit that I have not tried the latest Carl Zeiss offerrings for the Sony Alpha. Perhaps there may be something to pouring in a sufficient volume of money.
On the subject of a "normal" lens, I have always felt that the 58 mm focal length gave me the closest image of how I see the world through my eyes. When I raise my eye from the viewing port of the camera, everything stays in the same place; nothing moves.
