I bought a Cobra 121" last year from Ken's. They had the best price of anywhere that I checked including tracks usa.
They had a better deal on Ebay than their actual website. I called them and asked them if they'd just give me the price on ebay and they said go through ebay. Tried to save them money ya know.
If you find a better deal than Ken's, let me know. I'd like to get a new track. Probably a Cobra though. You should look into that instead.
