This isn't ideal, but we found a new straight for about 2,000 (total including shipping). Isn't state of the art, and we might have to spot her at the top of the stairs. If anyone else is interested give Silver Cross a call 1-800-572-9310. We have to install it ourselves, but 2,000 is much better than 4,000+.

I'll update again after we get it installed.
