You could always donate it to your favorite poster named Munch…
Those are awesome. Especially the MINI AT-ST and the Snowspeeder. They would look quite excellent on my monitor at work… guess I have to take a trip to KMart tonight. 
Yeah, I’d rank those at the top. Plus, you can always buy multiple of those and the X-Wing/Tie combo. The podracers are fairly lame, but you gotta get 'em if you want the bomber.
Slave I is pretty cool, though.
If you go to the Lego site, you can order 100 piece lots of specific brick sized for like 7 bucks a piece. You pick a colot, pick a brick size and you get 100 of them. For the size of a typical medium set these days you could have 700 bricks
If I WERE to get Mindstorms™, Id probably go for the system kit.

The standard RIS
