Here's a mini-ramble about the XL-15 set:
I bought the 76832 XL-15 Spaceship a while ago because I thought it was looked cool more than anything. It's been sitting on my desk for a few months and I think it's my favorite set.
While I've seen Lightyear, I wasn't a huge fan (it was fine, I don't have any problems with the movie, but it wasn't particularly memorable) so I can't speak much as to how movie accurate it is, but the overall build looks really solid. I'm a big fan of the cockpit (the way the joystick and HUD are integrated is really cool and it's a nice touch that there's built-in room for the robot cat), wing angles, and back storage compartments in particular. Originally, I didn't like the display plaque very much, and it would've been preferable it wasn't stickered, but over time it's really grown on me. For a set that cost me somewhere around $40 I'm really pleased. The minifigures are really good looking too and the custom helmets two of them get are really fun to play with.
