I didn't dare to say it at first, but the Ti-89 (and/or Voyage 200) were the first calculators I thought about when I read the initial post. And the Sharp E500 and E550 maybe. But of course all these are precious antiques now which can't be purchased in a stationary shop round the corner. With a little patience they can be found on the internet for small money though.

You can still buy brand new TI-89 Titanium calculators. I don't think they've been discontinued yet, surprisingly.
