For someone "... thinking about getting into photography..." to say "... I don't want something basic, I want something for a pro...'' is like a 16 yr. old getting his Learner's Permit and announcing he's going to start learning to drive by driving a race car.
The best way to "get into" photography is by beginning with a basic 35mm 100% all-manual film camera like a Pentax K1000 or Minolta SRT-202 or Canon FTb. Any of those cameras with a standard 50mm f1.7 lens and the Owner's Manual will give you (or anyone) a good grounding in photography. Buy a copy of "Object & Image: An Introduction To Photography, 3rd. Edition" by George M. Craven to supplement the camera Owner's Manual.
Enrolling in a photography class is the very best way to learn about light, composition, shutter speeds, ISO and f-stops but you can self-teach. Its harder to learn on your own but its possible.
Remember, its not the camera that takes great photos, its the person using the camera. The camera is a tool, like a hammer or saw or socket wrench or guitar or violin. Place any tool in the hands of someone who doesn't know how to use it and the result is chaos and poor results.
Would you rather listen to a concert violinist or a student just beginning their violin lessons?
Would you hire a journeyman carpenter to build a room addition or a student taking their first woodshop class?
Would you take your car to a certified mechanic for work on the brakes or have the kid next door, who just took a semester of auto shop, work on your brakes?
