What do you consider "inexpensive"?
Personally, I've gotten-by for many years without an oscilloscope at home, but I do have a couple of Tektronix 'scopes on my benches at work and once or twice, I've brought a hobby project into work, or brought an oscilloscope home. Sometimes I "lust" for one, but there's the cost, I've got too much "stuff" already, and I haven't really-really needed one.
But, I wouldn't buy one of those super-cheap "oscilloscope boards" (I think there's a board-kit) or cheap USB 'scope that uses the computer's display. If I was buying one, I'd get a "real" benchtop 'scope and I'd expect to spend $500 - $1000 USD.
At least one (and maybe both) of the Tektronics 'scopes at work were purchased used. We bought it from a reliable source that rents & sells test equipment so it was fully tested/verified/calibrated and it came with probes. We haven't had any trouble with them and they are calibrated once a year. I don't know what we paid, but I'm sure it was more than my "imaginary" $500-1000 budget.
I wouldn't buy one from eBay and I wouldn't buy an "antique" analog 'scope.
