I un-second it, if that's 'a thing', I think that was solid advice 10+ years ago, but not any more. The decent ones are less often seen, and they're collectors' items so they go for more than they're worth (to the audience the advice is directed at).

Unless doing something very particular straight off the bat (like audio or power or something) a beginner is better advised to get a cheap MSO / multichannel DSO, IMO, even computer based.
