This set easily is above average for me. I had this as a little child, and whenever any of my relatives came to visit us, they brought me some Lego. Usually it was either this set or 6844
The really nice thing about this set are the alternate builds.
For the low price you got a nice range of parts and cool ideas what to build with them. You could build a fleet of Rovers, or the alternates, and everytime it was huge fun :)
