Thanks guys. Well I was able to get (4) O54 switches off Ebay as well as the O72. The O72 was a little pricey, but I got some of the O54 switches at a good discount. I also won an auction that was posted for a track bundle. It included all the 4.5, 5,5, and 1.75 straights as well as a few 10 inch straights.
Jim I will send you an email.
