I just knew there would be a forum of Lionel train enthusiasts to guide me. I would like to buy a good quality starter train set to add to our Christmas tradition and add trains each year. I have two young boys so I need to be realistic in what I buy -- as in don't want to buy something very fragile or expensive because the point is for them to be able to enjoy. Can anyone direct me a good starter set in which I can add to annually?  Are there any particulars I should look for when buying?  Also where is best retailer? Lionel website? Amazon? Thanks!
