My favorite oscilloscope is my 2230.  I did not buy a Rigol because as
far as I was able to determine, they do not support single shot peak
detect.

The more I use my 7000 series oscilloscopes the more I like them. 7A13
differential amplifiers allow safe probing of offline switching power
supplies, the dual independent time bases can trigger from and view
separate asynchronous signals, and the samplers while tricky to use
are great for high speed design.
