The first thing that came to my mind were the new Legos - theres a bigger variety now. I would have gone ballistic as a kid xD
Since money is not a barrier, I'd go for a remote controlled helicopter with a go cam, or a hand held gaming console. I actually would have saved up for either if they were available.
I was thinking about the new video games that are advertised on TV, but then they would probably suck on an old black and white tube TV. :)
I cant think of a one. I had horses growing up. And alot of wilderness. I wouldnt have had it any other way
