Dale, if we're ever in a nuclear war, I doubt my first though will be "does my 'scope work".
Chuck, I don't think I'd start with the Rigol, but it's a fine unit. He can have a decent little unit for $100 or less, certainly less stress than screwing around with an old tube unit. It'll also be a digital model, which is far more useful than the old analog ones.
Agreed on all. But for new, the Rigol at $399 is a bargain I think. It has a built in counter, multimeter of sorts, and digital storage. And comes with two probes. I thought it was a show special when I bought one, but seems like the price is holding at this level. By contrast, the least expensive Rigol multimeter is $449. Go figure.
