You can't go wrong with North Central. As others mentioned, there are also other good choices in the Midwest. Greg Huffaker at Illinois Wesleyan is a a North Central alum who is a great coach. The same goes for Jeff Stiles at Washington University. Wash U is really hard to get into though, just like U. of Chicago.
While all of the UW schools, Wash U, NCC, IL Wesyleyan and U of Chicago are all good, established programs, there are also some up-and-coming programs with good coaches that are worth looking at. Benedictine has a North Central alum coaching there that is doing a nice job and you might also look at Edgewood College in Madison, WI. Their coach ran at Wisconsin and was a multi-time Big Ten champion who has done a great job improving their program in a short period of time.
Either way, the Midwest is a great region for a ton of quality D-3 programs. You have a multitude of good options. Good luck with your search.
