Rigol DS1000Z series vs old 1052E:

It's not just cuter, the bigger screen has a much higher resolution and, 
low and behold, can actually display information on that thing ;-) In 
fact, a lot of information.
You can also show waveform + FFT at the same time *and* actually 
recognize something (as an example)
It also has intensity grading, the DS1xxxZ not as fine a resolution as 
the 2000 series, but it's already nice.
(it simulates behavior of the phosphor of analog scopes, in that more 
frequently hit  parts of the screen will be brigher, which will bring 
funyn behaviors of your signal to your attention which might otherwise 
elude you)

You ca also store captured waveforms by points instead of by image, i.e. 
much more usable for post processing. I have not really further looked 
into whether there are tools meanwhle to read those files other then 
direct import in their software, though. Apparently you can communicate 
with the scope and ask it for data, not tried out yet. i thik the older 
Rigol could partially do this also.

Siglent supposedly also improved the quality of their gear, maybe their 
current models is more to your linking, I'd look at the eevblog teardown 
threads if they exist for that, though, to get some idea if tghere are 
problems, I don't know.
Siglent SDS1104X-E would be the contender to Rigol's DS1104Z, I believe.

Ah, looky there:

The user named "rf-loop" seems to strongly prefer the Siglent, and gives 
reasons for it.
But it's (was) also more expensive.
