Is there public transportation from O'Hare airport to Midway airport?

I found this: http://www.coachusa.com/wisconsincoach/ss.details.asp?action=Lookup&c1=Chicago+Midway+Airport&s1=IL&c2=Milwaukee&s2=WI&resultId=195952&order=&dayFilter=&scheduleChoice=&sitePageName=%2Findex%2Easp&cbid=152092489141 It is $39.00 one way. I haven't tried it yet, but looks like a good solution.
