So I have pinball capital in a Theatre of Magic, but I think we are ready to trade for a modern generation machine. The boss (wife) has blessed this transaction under the condition of not a single extra dollar spent, so it must be an even Steven trade. My boys and I are looking at Iron Maiden Pro and Avengers IQ Pro. What else do we need to look at in this price range ($6-6.5k)? Will I regret trading away this DMD classic?
