Picked up the Peril in Peru Lego set at Toys R Us yesterday. The TRU price mark-up was a little hard to swallow (I should have done some searching online before getting it, but I was out of town at the time and there is no TRU in my immediate area at home.) Anyway, I got it home and was really impressed by how hefty of a set it is. The plane is massive, and MUCH nicer than the Flying Wing set, which suffers because of its big plastic one-piece wing. All the little extra vehicles and cargo pieces are a great touch as well, and the Spalko mini-fig rules.
All in all, I think it was worth the money, but this will definitely be my last expensive Lego purchase for a while. (I'll start small with the new summer sets and probably milk a few of the pricier ones out of my family for my August birthday.)
