Heavy Duty Load Cell > 200 lbs

Does anyone know of any Load Cells compatible with Arduino that are capable of reading above 200 lbs with minimal lag? The use would be comparable to the sensor being placed on the ground and individuals running/jumping on it. I've done some searching and only turned up with a max weight of 50 kg which would be fine if I were to use two however I'm guessing the force from a foot landing is much higher than the actual weight of the individual. Thanks!

Take a look here for an idea of what is available. http://www.omega.com/guides/loadcells.html
