I saw your comment about wholesaletrains and just wanted to add the following:

I've ordered from wholesaletrains on many occasions http://www.wholesaletrains.com/ and never had any complaints. Their prices are good and their delivery has always been satisfactory. The only complaint I have is that your shopping cart gets emptied occasionally. When I want something, I have a tendency to place the order in my shopping cart. It may take weeks to fill the cart so I can take advantage of things like free shipping or other promotions. On the wholesaletrains site, they will empty your cart occasionally; thereby causing you to lose the list of items that you wanted. I have discussed this with them and been told "this is just the way our software works". I think they are working on this, but it was not fixed on my last order. Still, all in all, I shop there often - even if I do forget to order things that I really wanted.
