S Hawkins:On page 3 or the June 2009 Model Railroader magazine that I just received is a full page ad for an online auction wite just for trains. It is WWW.GOMOTORBIDS.COM/TRAINS I hope this helps. We are in HO and use evilbay and like you find poor communication from some sellers and wildly inflated shipping/mailing costs to Canada.

Good Morning,
I tried this site last month and all does go well until the shipping part.
They only use Courier Services and not the postal system so it my case for one piece of rolling stock the courier charges were more than double the final total of the auction.
Here is another site to try as you deal more with the indidual seller and can come to some common ground on how you want your purchases shipped. hoyardsale@yahoogroups.com. Sorry, I don't know how to make the link, (somebody help )
But to speak up for E-bay, I have made over 360 purchases from that site and 99.5% of them have been successful. You learn to avoid certain sellers as they really do gouge on their postage.. Be sure to re-read and study the auction (total description and terms of sale and shipping ) before bidding. (Know what you are bidding on and it's condition to avoid any surprises) I only use sites that take Paypal and if you do this you'll not likely have any problems.
Johnboy out...............
