About 15 years ago, we got a new Tek CRT 'scope

tried it out, and to me the trace wasn't sharp. I complained to Tek, who
claimed it was within spec, and asked what I was comparing it against.
said 'My old 555 at home'. Their comment was that the old 500 series had
wonderfully sharp traces (if correctly set up), and nothing afterwards
comes close...
The only one I've seen that does (my first was a 545A) is the 453.
NOT the -A variant, but the original 453. Fantastic trace quality.
Now, if you
could find an HP LogicDart cheap somewhere ......?
Good luck :-). That's a wonderful instrument that was totally
mis-marketed by HP, so nobody tired to buy them until it was too late :-(
I agree. They fetch serious money on eBay. HP has a history of
discontinuing products when there's still significant demand. Dumb,
dumb, dumb.
