Where can I buy a retro boombox?

I want to buy a retro boombox, but i don't want the kind with an ipod dock. Just an old retro boombox, that looks like this http://www.google.com/products/catalog?client=safari&q=retro+boombox&oe=UTF-8&cid=16671571109216145964&ei=REoETPLzGIrkNcqXjI4J&sa=title&ved=0CAcQ8wIwADgA#p minus the ipod. Where can I get one? Thanks.
