Second on the bench vice, so overlooked but it's another tool that can be such an asset.
Benchgrinder is also good. My Aldi one I adapted to become a sander with velcro pads on it instead of the grinding wheel and the belt sander end got removed in favour of a polishing wheel. Works a treat in my opinion.
Piller drill is good, but get one with a decent motor, too much pressure and the motor could actually stop if you're drillling using a hole cutter for any reason.
Scroll saw. Yeah might be good, but it does depend on what you're going to use it for. Leatherwork and thin wood would be fine, not sure about metal. They don't cut straight lines very easily and tend to wander off so just be aware of that. Same with a bandsaw. I have one but I tend not to use it that much as it's such a sloppy tool making the saw cuts zig-zag all over the place. But it does a good roughing out shape so I can finsih it by hand afterwards.
If you're going down the power tools route, I'd also recommend. A drill mains powered), a good battery drill, disk cutter, circular saw, jigsaw (Preferable a B&D Scorpian), a power planer, and a dremel or similar clone with assorted bits would be a good starter kit.
Good luck and if you're able to get on a basic safety course for how to use them if you're not familier with hand tools. They bite in the hands of the unwary. I kid you not!
