I have had a wide range of pins. I've owned MM, MB, TZ, STTNG, LOTR, CV, ToM and many other A titles.
I can honestly say that JM is in my top 3. I love(d) that pin. The flow, the speed. The theme and unbalanced scoring kill it for many folks. In the past 6 months, I've sold my MM and MB. I have gone all Stern, but I might consider getting a JM again. IMO, one of the best bargains around.
Cabinet fade is a concern but typically every JM seems to not have any PF wear. (Unlike MB and AFM)
Man, I am getting nostalgic.
