Fantastic scope! I use one. The 300MHz comes in very handy, trouncing all the budget DSOs at 100 or maybe 200MHz. You also get four channels, which is highly desirable. The cursors provide voltage, time, and frequency (see the manual) measurements.
I feel analog scopes let you truly learn how to use a scope. All the knowledge will translate to a digital scope, and you will know how to use it much better than someone starting with only a DSO.
As other have pointed out the single shot is not captured digitally. You can still do so with a camera set to bulb exposure (turn out the lights, open the shutter, capture). Single shot capture is a specialty thing I have rarely had a use for. It can help you see overshoot in a power supply, or capture digital pulses, but a logic analyzer is the right tool for that anyway.
:-BROKEI would HIGHLY recommend you open it up and recap the low voltage power supply It does not require re-calibration, and these supplies are known to have caps that fail. Even if it seems to be working there are likely blow line caps in there.
