Two for me, please. If my count is correct, and if people who said "1 or 2" actually take 2, then I'd be down for #53 an #54. From some of the posts, I get the impression that some people may be putting their names on a Frisco site list. Is there more than one list??
Accurail's custom runs require 48 minimum. Of course the cost is a little higher than if there was an order of 100 or 150. MP version of the 50' Boxcar: http://www.accurail.com/accurail/art/5000/5019.jpg
I have used Accurail for the past six years for an annual custom car for my club, and I have nothing but good things to say about them. They have always been a joy to work with. It is true that their minimum run is 48 cars, and that the more cars you order, the price drops a little, but only by pennies. Every year, regardless as to the car type used, number of colors used, and number of cars ordered, my club's cars have cost in the $17-18 per car range. Although 48 cars is their minimum run, you can order in increments of 12 above that number, for example, 60 cars, 72 cars, 84 cars, etc. Although you may not get a 100% prototypical model from Accurail if you're trying to replicate a specific prototype, I would think they are worth looking into if the numbers just aren't there to justify a multi-hundred car run from one of the other manufacturers.
