Not exactly sure what a sunk cost is, but if your saying that because you already have a motor that you bought before, it's not costing you anything, that's seems silly to me. By that arguement the cost of either of these system varies depending on what you have already.
How can the cost vary from person to person? You need to compare apples to apples when trying to figure out the cost differences. I would think even a caveman would understand this.
Like this (as Roland stated):
Single cell/540 motor
1. ESC $150
2. Motor $75
3. Battery $50
4. Regulator/booster/rx pack $25
2S/380 motor
1. ESC $50
2. Motor $20 (seems low to me)
3. Battery $25 (seems low to me)
It's obvious that the single cell version costs more, fact. If I had to buy one of these systems, cost-wise it is a clear decision.
