How about a Doosan Mynx – CNC, 22kW, 6000rpm, 30 tool auto-changer, and a table the size of a double-bed? If you need to ask the price, you can't afford it!
As always choosing tools, purpose changes the answer. Small workshop high-accuracy suggests a jig-borer, but there's a good reason Bridgeports are popular for general purpose use. Beyond Bridgeports, milling machines get really big. Horizontals are good for shifting metal quickly, while Verticals are more versatile.
An unlimited budget catapults us into the world of modern manufacturing, where many CNC machines completely out-class manual lathes and milling machines. Made by firms most of us have never heard of! As they cost as much as a small country to own and run, very unlikely any of us will ever have one in his shed. Shame!
Ages ago I read a 'best lathe' debate on one of the other forums. The winner was judged to be slightly better at clearing the ton and half of swarf it produced per shift. (4 tons a day.) Must be nice to own the sort of lathe that comes with a conveyor belt, but I don't really need one.
