Any experience with Lego trains? DS has been asking for one consistently this xmas season and I'm really on the fence - so, so expensive, he never played with any of his Thomas stuff, where to even set it up. It's hard for me to believe this is going to be worth the $. OTOH, he loves all things remote controlled and if this got him away from pretend guns, etc. I'd be ok with that. And I had my own (non lego) model railroad that I loved working on for several years, I think I was a bit older but maybe not much (but also we lived back east in the land of basements and rec rooms and space wasn't an issue. )
