"toy look" may be subjective, i find the rigols to be toys in that aspects
both physical and screen UI
All i can say for now is: yes, it mimics lecroy in many of the good things, the touch user interface is very well implemented, roll mode is what it should be IMHO (read: scan mode like tektronix do) the firmware is solid in the sense that i can use it all day without crashing it, no showstopper bugs for me
There are some bugs, some things i would do differently, some things i would have to be added and all have been forwarded to whosit.
Ask away, i'll try to see if i can help you. Bottom line, for the price it's a fantastic product
and given the fact that it's the TOP of the siglent line it's not going to miss features because stupid market segmentation policy (for example, same scope platform, same hardware, different options availability like R&S do. See RTM,RTH)
