These are pretty easy to find and you can find them fairly cheap. I would recommend looking on craigslist.com first.
Also be aware that the American Acad of Peds says that "Limiting young children’s exposure to television as a medium during formative years of brain development...may reduce children’s subsequent risk of developing ADHD."
