Who makes the best O scale track

[Anonymous]

I am building an O scale layout around my sons room. I already have a Lionel Polar Express set that I will be using. I prices out the cost of getting Lionel Fastrack to fini***he layout (about 40') and was suprised how expensive this stuff is. I was wondering if anyone out there could suggest an alternative. I have read on some forum's that Fastrack is very loud so I really dont mind switching to another brand. Thanks in advance for your suggestions.
