FREESCO replacement 4 commercial routers

I need to create more segments on my network and was looking into using an expensive PC as a router. I will not pay for NT so I was wondering if anybody has anything to say about using Linux for the task of routing. This link http://www.freesco.org/ says it can do it with an OS that runs off of a floppy. Anybody out there use this program? Let me know what you all think
Thanks.
