What are everyone's thoughts on this after EOL?

I don't think it's got long left, it's currently 30-35% off here! it has been cheaper but wondering whether to get a few

The EOL other sets from the marvel superheroes range seem to be appreciating nicely, but largely due to good minifigures (6866, 6865) (sold all 16 of my 6866 now for 3x what I bought, but think that was largely due to Deadpool and magneto, still hanging onto my 6865s for now)

IIRC Kmart and Target had them for around $23 during this past holiday season.  I think Walmart also clearanced these at around $17 (or at least they did in my area), so the buy in was pretty low for people in the states.

Unfortunately with so many sets containing Iron man now, the character has been saturated. It is going to be a tough sell to get his sets to move much above retail I feel, similar to Spiderman sets. The cheaper you score them the better. 

My son and I built this yesterday.  It's a small build, but the section of the mansion is nice. I feel like getting 2 more to make the mansion much larger.  The helicopter is very solid, but just another helicopter.
