Same, when I first started Odyssey I bought an iEagle, thinking like OP and the others did, but then I got curious about the iCourier and now it's my one true love. Now that most of my on foot weapons are engineered or close to done I'm finally starting on engineering my ship, the first step being the engine. So far I've only gotten to G3 dirty, hoping to add drag once I get the mats, then I'll work on the last 2 levels. Even at G3 though the increase in speed is exciting.
Though I'm a bit disappointed that the results are random, I had no idea that was the case and I have no idea what the max possible result on a "roll" is
