The EEE ship _might_ be a good investment, but hard to say. Lots of people hate the stickers, others not so much. It'll also be a long term hold set as it seems to be a set that was moderately bought by investors and is not lingering at retail. Nobody is sure what that really means... do people not like it? Maybe... or are people passing on it and may later regret that? Possible... who knows!
The train is a great set but it has doubled in value already. If you can get one anywhere near MSRP, it would be a rare find... Doesn't seem to be too heavily hoarded but where is the limit? 3x, 4x? Who knows!
Personally, the modular buildings are great investments. They might be heavily hoarded but they are also one of the most popular lines... there will be buyers for them, eventually.
I suggest you read up on opinions on this site, come up with a strategy (invest only in X, diversify with 1-2 across A, B, C, hold for 1-2 years or 3-4 or 10 years, etc). No single answer is right except have fun and don't go broke doing it!

Oh, and welcome!
