We bought hickory flooring manufactured by Bruce Flooring with a urethane finish from Home Depot. We are very pleased with the way the floor turned out, and it has held up very well with our five dogs and four grandkids so far.
Unfortunately I cannot recommend a contractor to install, though. The guy we used did great work, but he stiffed us on some other work thta we gave him a deposit on to the tune of about $500, so I am too pissed to recommend him. He is lucky, by the way, that I did not go Google-bombing his name with phrases like "unreliable" or "rip-off," but I retain that option if the dude keeps jacking us around (we got tired of his BS and used a different contractor to finish the job in question). Our kitchen is about 20'24', plus we have a 4'×12' hallway we also floored, and on sale the wood and materials cost us about $1200. The labor for the floor work was about another $1000.
Anyway, here is a section of the floor; this was part of a complete kitchen remodel we finished a few months ago:
I should add that the phrase "we finished" is somewhat misleading; we contracted out almost everything, and my labor was largely limited to cosmetic jobs like painting and patching drywall, while of course writing checks for the skilled craftsmen and workers who actually know what the hell they are doing.
