You could buy more tools, but, as someone who has bought some tools that sit with little or no use, I'd get into making those projects you listed. Once you're into them you will find out what you need. Sounds like you have enough to get started. The Domino is a great tool and makes mortise and tenon joints simple. However, if you want to learn about woodworking, I'd suggest cutting some mortise and tenon joints by hand or saw or another method. If you are looking for a fast and great way to make mortise and tenon joints, that's the Domino. I wouldn't suggest buying the 700 with the adapter as many do suggest. The 500 and 700 are much different tools and really each made for a different scale of project. The 500 for most, possibly all, of the projects you list. The 700 for large projects. With the adapter, you can approximate the purpose of the 500 but never duplicate it. If you build both types of projects, I recommend both machines . . . Just me maybe. Also, Festool doesn't warranty the use of the 700 with the adapter, so that might be something to consider. Good luck on your woodworking. Having done it for many years, I can tell you that I always feel a great sense of satisfaction after making something in wood. There is nothing better than woodworking for the soul. So, my short answer to the point of the post is the 500.
