I don't know much about the 306 but I would definitely wait until half price day. Be careful with the mold...don't take it into your house until it is cleaned. And wear gloves and a mask when you do clean it. Mold can make you very sick. Just my piece of advice. The musty order can be fixed by leaving it in the sun if you can. Also check Billy's tutorials on how to clean it. His board name is Lostn51.
