This 10 dollar set is a bit small, but looks very good when completed.

Pros: Both the buggy and the alien ship are good, although the buggy is obviously the star of the set. The little ship can actually fight fairly against the buggy since it has 2 guns and the driver (who looks awesome) carries his own weapon. The buggy is very well done, equipped with two missiles and two laser guns that can be angled to shoot down alien ships, or put in the drivers hands. The driver is gonna have a hard time seeing over that front part, but it's got some neat detail. The buggy also comes with two little pistols as what i assume are exhaust pipes.

Cons: It's really more of a 7-8 dollar set but just a couple extra bucks isn't bad.

If you wanna check out the Alien Conquest theme, this is definitely the set the start with. I'm gonna get the tripod next.
