I just traded my WS1 for a new 45 for $165.
Call the factory and they will take your old WS1 in trade. They ask for $300.00 for a new one but when I traded mine in, all that was available were a couple of 'boat show' models that were in scuffed boxes that couldn't be sold as new. The 'boss' said they sell those for $150 + shipping. They tested it too before sending it. Important, because I can't test it until the mast is stepped when we launch in July. Those display models are hit or miss though, good luck.
