I will agree with the positive commentary on the StarCraft Legacy trailer. The look of the ships matches very well what was seen in the original game, whose models/vehicles I found much better than those of the new iteration.
A list of ships will be interesting to compile. I took a brief look through the ship list on StarCraft Wiki - not everything was necessarily there, or at least in that particular place. I did find the ship I was looking for, but it required a manual search.
Noting the ships in the cutscenes will be an interesting task if you go that far. Most of the ships are never seen in-game (such as the little transport shown bringing the demo team onto... Amerigo Station? Regardless, it's a useful ship with very few details provided) but would prove invaluable to it. Using Fraps could do well for capturing images for developing models.
Actually, I've had a heated debate about a realistic CF/A-17 Wraith before on a different forum. It could potentially add to your current conceptions of you who might-be-doing a model.
