NMO Dual band antenna Help

I am staying the night in Columbia, MO and was wondering if any one new of a HAM store that carries NMO mount antennas. My antenna broke in half driving down the high way. I'll search around myself tomorrow but thought i would ask if any one new of a place even in KC would be fine as well since im headed west tomorrow.

Thanks to any one who has suggestions.
been doing some searching i think i may have to try the local radio shack and see if they carry anything or if they can direct me to a place that does. Then i'll be searching in Kansas City.

If you stop in KC, I can show you a place in Mission (Around Shawnee Mission Parkway & metcalf). I've been trying to find it on the web and have been unsuccessful. If push comes to shove, I can just take you there.
