ISO Adult Size Elmo Costume To Buy

Hello, I represent a punk band from NY. Our new live show involves me rocking out on stage in an elmo costume - I was able to rent one and try it out a few times - it REALLY livens up the show and works great. Now that the band is ready to go on tour we need to find an adult size elmo costume we can purchase. They`ll be on tour for about 3 months and really don`t have much money to spend on buying one for a few hundred dollars. I saw on on ebay a while ago but now it`s not there. Please contact me if you know of where i can get one.
