I didn't even consider Wisconsin. We live in Lake Bluff, about 15 miles south of the state line. My husband has always been interested in moving there for the lower taxes! I will check it out.

Barrington could be an option, there are more affordable communities in that area (we moved here from Arlington Heights so I'm familiar with it).

(The drive from here to Quest was around 30 minutes when I was there for a lecture recently, I got there at 7pm so that should tell you about the traffic. I would count on it being upwards of 45 minutes each way in a lot of slow traffic, and closer to an hour depending on what part of Libertyville you're in).
