Since you are in northern IL, I'd suggest looking at Milwaukee School of Engineering (MSOE). I received my BSEE there in 2003. They are a private college, so tuition is more, but there is a lot of scholarship and financial aid packages to help offset. MSOE is focused on undergrad engineering and all professors are there solely to teach, so there are no teachers assistants, no faculty research taking away time from students, etc. MSOE also focuses on real life application, so the lab/hands-on portion of the curriculum is a point of emphasis (not just theory all day long). They offer computer science along with engineering disciplines in software, computer, electrical, mechanical and industrial. An alumnus made a large donation for a new computer science/AI building that is currently under construction. Being a relatively small school, I really got to know my professors and classmates. I would suggest taking a tour on one of the open house days.
