I live up north slumming it by Mitch
, but I've spent a good chunk of my career working in Fox valley towns and for the last 2 years I've been working in Lisle on the Lisle/Naperville border. Naperville has very highly rated schools but to me seems crowded and congested and it's $$$ to live there. If I wasn't rooted in where I am now I think I'd be focusing on Wheaton, Lombard, West Chicago and Glen Ellen in my housing search.
One thing I think is important to think about around here is traffic patterns. Traffic heading in the general direction of Chicago in the morning is awful and visa versa in the evening. But going the opposite direction is generally fairly clear sailing. I drive southwest 27 miles to get to work and barring an accident or snowstorm, get to work in 40-45 minutes on average. At work I listen to coworkers gripe about the traffic coming in from places like Aurora and Oswego, which are a lot closer to Lisle than my town. My manager bought a place in Naperville this year only 6 or 7 miles south of the office and complains about the bad traffic getting to work.
If the car scene factors at all in your search, the far SW suburbs have a pretty lame cruise scene with the exception of the once a month June to October Saturday evening Morris cruise (900 cars, don't miss it!). The best Chicago area cruises besides Morris are in Downers Grove, Lombard, Rolling Meadows, Roselle and Mundelein.
