We have a olympic level gymnastics school in central Mexico. We would
like very much to buy USED gymnastic equipment--- mats, horse, spring
board, equilibrium bars, parallel bars, etc BUT is still of such good
condition that it could be used in strict requirements of competition.

Did you ever buy any equipment for your gym?

The question was to help some friends that a developing Olympic
quality gymnists. They have a most limited budget. No. They were not
able to buy very much. The gymnists must train on first-class olympic
grade equipment or the "learn" wrong.

FYI - Easily the best place to find used gymnastics equipment (or any
other fitness equipment) is www.usgyms.net then click on used
equipment.
