One privatized option is the New Pullman service that will start in the fall. Definitely not cheap, but more affordable tha the late American Orient Express. There is a thread here:

And just for fun, here is an interesting take on the American Orient Express:

We'll see what happens.
We have discussed this before, and I wish this new service well.
However, we shouldn't fool ourselves into thinking this will develop into a proper public service comparable to Amtrak's own cars. Private operators will cherry-pick routes (and I don't mean that negatively), and the number of customers interested limits the number of trains they can do this. Right now they are looking at a twice-weekly service on two different trains. I don't expect it will ever expand significantly beyond that.
It's like crossing the Atlantic. I can catch any one of several dozen flights that leave every day. Or if I want to go by ship, I can choose from maybe one or two saliings a month (in the Summer, probably nothing in the Winter). Why aren't there more ships and more sailings? Because that's all the market will support.
You can argue, the ship isn't that expensive. It probably costs less than first class on the plane. And it's much more comfortable in every respect to be on a ship. But the problem is that many of those who occupy those expensive seats on the plane are business travellers, and crossing the Atlantic by ship is just not really compatible with the schedule of a businessman. Trying to think otherwise is to chase a market that bdoesn't exist.
