A few months ago I bought a portion of a guy's toy collection for a hefty, but reasonable, price with the intention of reselling them. Probably paid a little more than I should have but at the same time the return has been well worth it.
What I bought before was all Star Wars and G. I. Joe's which I am very familiar with and I know the resale value I'm getting. Now I'm in discussion with him to buy the remainder of his collection. Or at least a portion of it.
Problem is, I am not sure if some of the toys are worth getting. Some of them I know about and others I have no idea. Not asking for anyone to do research for me

, I'm doing plenty of that as we speak, but I am asking for your advice or recommendations.
I'm sure he's going to be asking a pretty penny for the entire thing so I might have to pick and choose from the most desirable items.
Here's the short list of what he has. There's some more but I don't recognize them.
Dino Riders (says it's a nearly complete collection including Ice Age, Bone Age
Other World from Arco
Robotech SDF 1 Playset
Robotech Zentraedi figures
Sky Commanders
Guns of Navarone playset
also a whole bunch of metal toy soldiers from the 50's I think
There are a couple of big GI Joe vehicles that I'm struggling with. He has the USS Flagg aircraft carrier, Defiant Space Shuttle Launch Complex and the Cobra Terrordrome. I really, really, really want those - especially the Flagg - but the space they will take up, the rareness that those sell and the difficulty in packaging them up for shipping makes it a risky purchase. Not to mention that the shipping I would have to charge would be a really tough pill for a buyer to swallow.
I'd love to hear your thoughts!
