Question on ModelTrainCrossing.com's reliability

I have been searching FOREVER to find cars that would represent those run in the “Super Chief” trains (in N Scale). I know that Con-Cor/Rivarossi ran a set of 5 cars that is out of print now, so I was very excited when I found a dealer selling this set on the internet. However, this dealer is claiming that there is not just this set, but a second set available as well. The dealer is also selling these cars at about $16 bucks per car. This sounds low to me for high quality manufacturers such as Con-Cor and Rivarossi. The name of the website is modeltraincrossing.com. The page containing the cars in question is here: http://www.modeltraincrossing.com/con_pass_sl.htm

If anyone could give me any information as to the validity and/or reliability of this dealer, it would be great. I’m afraid that I might get ripped off.

If you are willing to put a little extra energy into it you may want to try hunting down some brass car sides or plastic car sides. Check out this link. These take a little work but can provide you with something great once complete!!

If I recall, con-cor is preparing to close its doors. The price might be a reflection of the company clearing out stock. I looked at your link and see that they are selling open stock too. Maybe purchase one car and see how they look before oredering the rest.
