My list from the five I have just finished (and had help finishing) from easiest to most difficult: IJ, TZ, TOM, JD, and TAF. The TAF was hard because there is no playfield slide out mechanism. The playfield is either up or down. It was also the machine with the most issues for me. Every time I took something off I would find a new "discovery". The MPU board was declared by many as "the worst I have ever seen". It just never ended with this machine.
