MY ROBOT COSTUMES ARE FOR SALE!!
A few caveats, the costumes have been stored indoors 100% of the time but the steel components were not painted so they have some surface rust (makes for a nice distressed patina). The current state of the costumes requires tying ones self into the costume (with the help of another) which we used bailing wire for. They are large bulky items so shipping will likely be fairly high. Local pickup is available in the Seattle/Tacoma area or maybe "Greyhound Freight" would be a cheap option.
Make a reasonable offer on the pair and they can be yours! The detailed build of the costumes can be seen at the instructable below:
