I think in the end those people holding on to A-list DMD games hoping that they retain/gain value (MM included) will get a rude awakening. We've seen the future from JJP (LCD monitors) and that can only mean that (if that technology is widely adopted by all manufacturers), the DMD's will start depreciating like the EM's did. New buyers will start a shift towards LCD games and look at DMD's the same way you look at an old score reel on the old machines. Probably not something that would happen in the next 2-3 years, but more like 10 years. If Stern starts using LCD's to compete with JJP, watch out! I agree with Houseofpin, buy them and enjoy them. Pins should not take the place of your 401K/retirement plan!
