Hi! I'm not sure if anyone is interested but there are 10 or 11 55 inch long Star Linear rails on ebay right now for $95 (Buy It Now) each. It seems like a decent deal to me. Here's the url:

I would buy some but I've already settled on 43" long x-axis rails for the router and 55" rails would require me to get longer x-axis aluminum extrusions and a longer ballscrew.
Good luck!
