I have two large binders of past EE qualifying exams with solutions for $10. This is one of the biggest sets collected so far.

years include:

1990 - 2005 complete set

also, a big set of very old questions from the following years:

1980
1982
1983
1984
1985
1988
1989

These are collected through years by students so it would be very hard to find anywhere else.
