looking for disposable uni

Hey I am headed back to mexico for christmas and am looking for a unicycle that I can pretty much take and leave there. We will be scuba diving and hopefully will be able to film some underwater unicycling. I am looking for like maybe an old torker lx or some other basic uni that i can pay shipping and a minimal price for. Hopefully this will be a fun project. Pm me if you have anything laying around.
