I have been using Accuratic winders for a nearly a decade I have 7 of the first generation ones and 10 of the second generation ones (aluminum housing), they are the best winders on the market.  If you ever need to add more they are modular, with the right coupling pieces you can have 1 or 20.  The newest models are even better and more refined than the first generation plastic ones, better watch holders, even quieter (if that was possible) and more customizable.  Now I did have a small issue with one of of the winders I just ordered, I emailed the company, they called me right away the next morning, apologized, explained that they are built to be easily user serviceable, and they are sending me all the parts to remedy the issue right away, I couldn't be happier.  I would recommend getting felt pads for the bottom of the winder(s) because the edges are anodized aluminum and could mark wood
