Well lets see I have had TZ for 5 years, Wh2O - 4years, IJ- 4 years, AFM for 3 years, and BSD for 6 months and no plans to trade or sell any of them. The only Stern I still have is LOTR- 3 years. Tron and Iron Man lasted 3 months each . They were both a lot of fun but they lost something. I like most of the newer Sterns but I feel some are too similar and not worth 5-8k.
