I'd generally agree.

In my experience, during development of new digital hardware of any
complexity, both a DSO and a LA are extremely helpful, but for
diagnosing failures of previously working hardware, the DSO is usually
more important.

If a person has any reasonable business justification, a Rigol
MSO1104Z mixed-signal oscilliscope (100 MHz four-channel DSO with
integral 16-channel logic analyzer) is under $1000, and for another
$230 you can get the model with the -S suffix, which also includes a
two-channel waveform generator.  I generally don't recommend cheap
Chinese test equipment, but the Rigol stuff is actually pretty good.
