I learned to woodwork by watching Dad on the 10E as a kid. My needs have gone well past the old girl but I still use it for disc sanding, long lathe and drill press (rare as I have a dedicated DP). (I have a full woodshop. Delta, Powermatic, etc.)
The 10E is obsolete but not trash heap yet. Get a good Mark 5 or later. I'm gonna get a "you ****" here but I picked up the headstock unit for a Mark 5 2 weeks ago on CL...FOR FREE. The guy had purchased a newer replacement that is digital and has lots of presets and was just giving it away so I'll be checking it out and using on the 10E bed maybe, (If the rails haven't changed in 60 years.)
By the way I gave the guy $40 as a donation to his church. He was a minister and would not accept cash until I called it a donation. Seemed like the right thing to do.
Back to topic, the Shopsmith is good. It is a "jack of all trades" tool. It is good at lots of things but not great at any. But to get all the stuff in your garage that comes as attachments to the Shopsmith would cost lots of cash, take up lots of space. The benchtop tools mentioned above are equally limited by power so I have personally steered away from most benchtop tools.
The one thing I absolutely hate about the SS is the tilting table instead of tilting arbor. That's a big limitation and a little scary when cutting long stock. It will make you want a miter saw right away.
Good luck, let us know what you do. Rick
