i for one am glad its not a larger scale set. i really, really like what lego has done here with the mini sets.
i don't have the money it takes to support a "hardcore" lego habit, and neither do most kids or kids parents. not to mention that system sets aren't usually as nice as they "should" be.
anyways, i see stuff like this in pluses and minuses. here are my "two cents".
PLUSES: this gives everyone a chance to build a fleet of these things for relativley cheap, if they can find enough of em on the pegs or sideclips that is. its not another SSD or RBR that only people with lots of loot can afford.
MINUSES: don't see any right now...two thumbs way up!. ask me later though
