Certain em's (the better players) just don't seem to pop up that often especially in the part of the US where you live. Granted, some parts of the US like the NW, west, etc. just didn't get the games back then like others. Low production games are more understandable. Also, "B" and "C" title games come up for sale more often - makes sense.
Here's a few that I don't see come up for sale that often in the Midwest:
North Star: Seemed to come up for sale in the NE but not in the Midwest as much - I did find one courtesy of dirtflipper though
Lawman, Sheriff: Don't see this multi-player that often here in the midwest
Snow Derby, Snow Queen: See this come up in the North, NE more
2001: 3 or 4 years ago I spotted a few for sale and then it went dry again.
Target Pool: A few in the last several years but not many
Easy titles to find in the Midwest recently in the last few years:
