They are both useful. You don't even want to know about all the bells
and whistles you can get, let alone trying to figure out how many of
those whistles you can use, not to mention the bells. And the digital
models are like a high end ham rig. You are going to be navigating
tonnes of menus.

I'd go for an analog crt based scope, 20mhz, 50mhz or 100mhz bandwidth.
With a 50volt to 50millivolt input range. Make sure it comes with a
probe with 10:1 input switch. Scopes typically have a 1meg ohm input
impedance so the 10:1 would get you 11 meg input plus the probe offers
frequency compensation.
