[sdiy] Another "getting started" question

[Steve Begin]

I recieved "The Art of Electronics" and the student manual a couple days ago
and I've been reading it (although I think I may need to re-read earlier
parts once I'm done everything) and so far it seems excellent.  Pretty much
exactly what I was looking for, so thank you to everybody who helped me out
there.  

Now, I've got another question.  I used to have an old vaccuum tube
oscilloscope (got it for 20 canadian) that was pretty okay (I really only
used it to help to understand the way waveform shapes correspond to sounds).
I think eventually it just stopped working, maybe a tube burnt but either
way I can't find it anymore, after that I got another oscilloscope free from
a friend of a parent, I think this one was solid state but it seems like the
fan stopped working then so did everything else.  Now I have a heathkit
oscilloscope from 1954 and it works, but it doesn't have markings on the
screen and it doesn't seem to be much good for measuring things, I'd
question it's accuracy as well.

So...I'm considering buying an oscilloscope, and I really don't know what to
look for, or where to look, or what to expect to pay.  I'd appreciate any
advice whatsoever.
