If you cannot find one here, you can check eBay or Craigslist. Of course, be careful and make sure the seller has a good reputation and (for eBay) a good feedback score. And be careful about pricing. I spent quite some time looking for a second PSR-E433, and while I would often find them for sale, the sellers were asking what I feel were ridiculous prices for them, especially when shipping costs were added. We're talking about prices sometimes exceeding $400 US when including shipping, for something that had a street price of $250 US brand new.
