I don't know where you're from, but I was able to pick up a copy of Starsiege in a shovelware bin at London Drugs for about 10 dollars. Also, for any interested in Starsiege: The Tribes, Vivendi/Universal also has it available for download from their own website. It probably has a better bandwidth than most other places and it's your duty to cost them money for ruining the _____ Quest series.
k: (even if it's only pennies)
