I'm going to be honest here, you won't find a new machine as good as a Singer 201. There are definitely some great new machines available, but none will still be humming along at 70+ years old. And with computer parts and mother boards and such in all new machines, even the Juki 2010Q, you will need to bring the machine in for a service, rather than doing it yourself.
If you want a machine for fancy stitches, zigzag stitch, and needle down features, I'm sure there are some lovely machines out there that can do that. I use a simple Wal-Mart Brother, and now a vintage Pfaff 130 for applique. I just know that no plastic Brother machine will never be as nice as my vintage machines.
