In that case, this is our guy:
http://www.bricklink.com/store.asp?p=Alvi&bindID=30927
60 pcs straight 9V track @ ~$3.04 US (so $182.40 total, roughly, sans shipping. For 12 fewer sections than Laura’s guy, but still not bad, and less than the $340 that guy would charge.)
The track is part of a superlot so you we couldn’t just buy it alone, biggest problem is after looking through the store terms it It doesn’t appear they ship to the U.S.
