About $100 for both meters. The meters are held together with a rubber band.
Measuring terrible ripple from a buck converter ( 1.2 vpp on 3.3 vdc).
The DSO112 agrees with the Rigol, but the Rigol shows a high freq component that does not show up on the DSO112 (due to bandwidth). Both are using alligator clips. Really bummed over the buck, I ordered 5 more before I hooked up to the scopes. Probably will start a post on the buck (a big one with lots of ripple). My small bucks have little ripple.
I like the DSO112, I use it more than the Rigol because it is so easy (limited settings). But I am not using it for rockets.
