Should I buy a Rigol MSO5000?

So for what purposes you are using this amp you´ve linked ?
Please show pics from the amp and your scope how they are connected together and with the signal source and of course screenshots where you can see it´s behaviour concerning additional noise, phase-shifting and so on.
Thankyou!

Also, I don't want to curb your enthusiasm, but read along the tail of the other thread. If you want to find its limits, it will suffice that you do stuff below (say) 50 mV.

There has been a lot of discussion about the ADC noise of the Rigol MSO5000 compared with the Siglent SDS2000X Plus, which is more expensive (arguably enough of a price difference to notice if you are hobbyist, perhaps not if you will use it as tool of your trade). 

Instead of this comparison, I'm curious how is the Rigol noise compared to all of other those 'scopes costing up to and around $1,000?

A) Is the Rigol 'noisy' for a 'scope costing up to $1,000, or
B) Is the Rigol noise about the same as other 'scopes costing up to $1,000? 

Does the fact that the Rigol is being compared with the more-expensive Siglent mean it is already "punching above it's weight", but too much to expect a "knockout"?

See the capture Martin took where a $500 DSO was noticeably better than the 5k.
I linked it a couple posts back.

I saw Martin had kindly shared images from a Silgent, the Rigol and a Teledyne LeCroy.    Perhaps there are two different Silgents here, the first a $500 DSO and the latter ones the SDS2000X?

Exactly correct except for missing the Plus.  ;) The great little and very popular SDS1104X-E represents itself very well against many much more expensive.
