Legos, what to chouse. DS8 loves them, but now the only ones of interest cost way to much. 2 years ago we purchased the Eifle tower, he built in in two days and loved it, it still is on a dresser in his room. Last year we did Mind Storms, fun for about a week, but did not really take off. This year I have looked at the Melinium Falcon. DS would love it, But $499 is way to much for another build in 3 to 4 days and put aside. Are their any other building type toy ideas that have worked well?
