And why would I waste money to trade in my perfectly functional '93 Taurus on a new Chevy equivalent? The whole point of paying the cost of trading in would be to get benefits I can’t realize from the Taurus.
The point is that unless DCC is perceived as a serious and worthwhile upgrade to DC, then there is no reason to spend any money on switching from DC to DCC.
There are really several different scenarios being confused with each other.
The newbie starting out in model railroading, perhaps with the proverbial simple 4x8 layout. In this case, straight cost comparisons might be useful in the single engine/single operator case. On the DCC side, the Zephyr takes the place of the DC power pack. Not much benefit for the extra cost ($100+) of DCC in this scenario, unless the single locomotive is sound-equipped ($100 extra).
Next scenario - the 4x8 train set is expanded to 2 train/2 operator with several locomotives available. Now the DCC operational benefits of not having block toggles start to mean something. But the true cost of DCC includes: Starter system plus second throttle plus jack(s) for second throttle plus extra cost of decoders in locomotives (either bought with decoders or installed afterwards). Total DCC cost is in the neighborhood of $250+. Cost of DC is around $100 (2 power packs plu
