Thanks, can you give me a link on how to convert the sdm3045x to sdm3055x-e?

review that thread for other details. It's pretty easy.

Look again, it's much more than "touch screen bolted onto legacy interface".

Instead of being impatient, what about contributing to the community and do a thorough review yourself ;)
Seriously though, there are plenty "reviews" out there. They will show you how to unpack the Rigol and some fanboys will praise it to no end, even though they've never touched one, just because it finally has an acceptable noise level and a user interface that doesnt look like a slot machine.

Just to provide complete information on the SDS2000X Plus: aliasing isn't a problem even at low frequencies on a decent DSO with long FFT. For instance, we can analyze down to 100 Hz and still have 250 MSa/s for the FFT. Together with the 20 MHz bandwidth limiter and the 10 bit mode, which additionally limits the bandwidth at 100 MHz rather steeply, we don't have a problem with aliasing due to subsampling at all.
It is true though that general purpose oscilloscopes have a rather strong rise in noise below some 100 kHz, hence measuring very low noise will not be possible at low frequencies.
600 µVpp would be equivalent to 212 µVrms or -60,46 dBm (I use dBm even though we are talking about voltages here, just because my measurements happen to be in dBm). Consequently, we can analyze noise as long as the FFT plot does not exceed that level. As we can see from the attached graph, even at just 1 kHz, the measured level is still -96 dBm for 450 Hz bandwidth – way below the -60.46 dBm calculated before. Only down at 200 Hz we reach a noise level of 900 µVrms.
But then again: if you need to look just for mains hum and its harmonics – and 600 µV would be a problem for your circuit alrady, then you actually need a dynamic signal analyzer (expensive) or a PicoScope 4262.
