I wanted to reply to your message about buying layouts. The place is called Lloyd's Layouts-We see them at all the train expos-they are really cool-We are in the process of ordering ours now for an HO scale. Here's the website-Lloyds layouts.com or 562-470-6767. They are very resonably priced.
You have to be patient and try craigslist. Someone will move and look to sell a layout. THey go 300 to 500 for a smaller one. Unless you are particular and want a custon job. Just search layout, Lionel or MTH or O scale. To me that's the best deal. A couple of handy friends and you can move one.
