S.T.
Legos are such a good toy - it's good for so many parts of a child's brain development. Based on how much Lego sets cost this sounds like a decent price. My son is 12 and still spends lots of time with his legos. As toys go this is a great one. Plus he really, really really wants it. Don't you remmeber really wanting soemthing at that age? All I wanted at 8 was a pair of roller skates - the ones with the white leather boot. My mom asked me if I was certain - becuase they were so expensive it would be my only gift. It was a dream come true when I opened that gift.
Go ahead get him his dream - it's not like it's a video game!
