RangeFinders: IR vs. Ultrasonic

We're looking for a rangefinder for our robot for use for getting the right distance from the wall to shoot from. Now, I've done some research and found that the IR sensors are good when you have no ambient light (which would be the case indoors in the stadium) and Ultrasonic are more accurate. More accurate would be better, and I've been having troubles locating a good IR sensor that's no too expensive that gives us a minimum range of around 20 feet. As far as utlrasonic goes, we found the Maxbotics MB1240, it looked like it would work great. Unfortunately, we don't know if we should go with an IR sensor in fears of interference from the Ultrasonic Sensor (other than other robots, I can't think of other possible causes for interference).
