Illinois 5 - fluke win basically against 36 year incumbent who took seat for granted. A very urban district near Chicago that went for Gore in 2000. Blago picked this seat up in 96.
Illinois 11 - some rural and exurban areas south of Chicago. Basically a swing seat. The guy who picked up the seat held on to it until he retired 2008. Debbie Halverson however was unseated in 2010.
Indiana 2 - basically east central Indiana. The guy who was unseated was first elected after watergate. I don't know what the district looked like then, but I know Indiana radically altered the districts in 1981. I believe the guy who took over lasted until 01 when he retired and was replaced by Mike Pence.
Indiana 4 - same boat as ID 1.
ILL-05 - a hell of a lot more to that then just taking the seat for granted. More like felony convictions.
The predecessor to LA-02 (except riding a wave to victory rather than super-low turnout)?
