A two-channel 100MHz digital storage oscilloscope in a proper benchtop format, with a larger screen and dedicated controls. It is the step up from a handheld when you start debugging microcontroller projects seriously.
The DSO2C10 is the budget route to a real bench scope. Dedicated knobs and a bigger screen make everyday debugging much faster than a handheld, and 100MHz covers the signals most hobby projects produce. It lacks the polish and four channels of pricier models, but for learning and troubleshooting it is a very capable first bench instrument.

Compensate both probes on the front-panel calibration output before your first real measurement. Learn single-shot trigger early — capturing one event, such as a button press or a startup glitch, is what bench scopes do far better than handhelds. Ground the probe as close to the measurement point as possible; long ground leads add ringing that is not really in your circuit.
Hobbyists moving to microcontroller debugging who want a bench scope on a budget.
Four channels from a better-known brand, if you need to watch more signals at once.
Portable, with a multimeter and signal generator built in, if bench space is short.
