Wayne: Kerry Thallman wrote a very useful article in View Camera a year or two ago about his backpacking gear, and had praise for the Toho FC-45X as a light, inexpensive, full-movement monorail that he used for backpacking on a regular basis. I was trying to make a decision similar to yours (went with a Walker only because a field camera made more sense for me) at the time and recall seeing posts on photo.net and elsewhere that recommended the Toho as well.
Badger Graphic lists it on their web site at $1395, a bit more than it was when Kerry's article appeared. Might be worth consideration and you should be able to pull up some of those threads that I looked at while you're making your decision.
Good luck!
