Reason for ebay sale is because it protects the buyer (and the seller too). For example, I bought a used ep 500 for way more than I should have. And i didn't get to press a single real case. I pressed 2 dummy rings for testing and a gasket fell apart (which they dont make anymore). Told the seller and he wasn't willing to reimburse me any part of what I paid. So, I paid a huge amount so I could use the oven for scrap parts. Never will I buy something so pricey again unless it's ebay. Okay, done venting. haha
