Even if one could find a gently used ecoboost truck, it would likely cost more than it's worth and nearly as much as a new one. Even with fuel prices as high as they are, trucks and SUV's are holding incredible value.
Since the EB trucks have only been out for about a year, the low supply of used ones will keep the price up. You might want to see if you can find a leftover 2011.
Edit: As a quick check, I just checked Autotrader for used EB's in my area, there was only one. It was equipped about the same as mine and they're asking almost $5000 more than I paid new, and it has 9000 miles on it.

After thinking it over, a new one will probably be cheaper than a used one. When fuel prices are at their highest this summer there will be some better prices on trucks and suv's, but the market is usually a few months behind reality on prices. And with the supply of EB's low, I wouldn't expect any great deals on them until they've been on the market 2 or 3 years.
