I've never used one, but the Rigol looks about the same as any of the other Chinese oscilliscopes. Do you actually have one?
I used to have one at my previous company, they are very good value for the money and well made. I never found a single firmware bug or performance issue.
Rigol have a very good industry reputation, so good in fact that Agilent re-badge them as their own. All of the very low end Agilent scopes (e.g. 3000 series) are designed and manufactured by Rigol.
Rigol also designed their own front end samplers, which at the time was quite remarkable.
When Agilent first rebadged them they used to look identical, only the badge and firmware logo were different. Now Rigol have shot off ahead and produced a wide range of their own units. Seems like a new model is coming out every six months or something.
The other "low-end" maker with a good rep is Instek (Goodwill).
So basically, if you aren't buying Tek, Agilent, Lecroy, Hameg, Rigol or Instek, you are buying worthless junk.
