I just have to mention, after using the Rigol for over 3 weeks (my first DSO - I only had Tektronix analog scopes before), that even though the build quality and most of the firmware seems solid, a 5 1/2 screen is just too small, especially at 320 x 240, in this day and age of LCD proliferation (at least for my old eyes). It made me feel a bit like I was back on my old Epson HX-20 (except in color).
My next purchase will be 7" minimum - either the Hantek - or perhaps one of the new Owons - which have 8" screens (that's more than 50% larger than the DS1052E), huge sample lengths, VGA output, and are competitively priced against the Rigols.
