O-scopes: probes, tutorials

A couple weekends ago I finally made it to the Flea at MIT - only
been meaning to go since 1989... Anyway I was looking for a vendor
and wound up watching an exchange between a different vendor and
this guy in a corduroy jacket. The short of it was, this vendor was
desperate to not have to load all the Tek scopes he had back into
the truck. Corduroy boy was balking, and the vendor only got more
flustered when he was asked if the scope could be hooked up to a
stereo to do something cool ;^)

So I watched this play out. I'd been thinking I should pick up a
scope, as I hope to start tinkering with hardware again sometime
soon. But I was thinking about some simple dual trace 20-50 MHz
unit...

What I got for $100 was a Tek 7834 Storage Scope on a Model 3
cart. With the following 4 plugins: 7A22 differential Amplifier,
7A26 Dual Trace Amp, 7B85 Delaying Time Base, and 7B53N Dual Time
Base. And upon getting it home it did, indeed seem to work. Of
course I have no probes or manuals, but I got traces and labels
and whatnot on the screen. Calibration? Who knows...

Anyway, I was wondering what my options are for getting some
probes for this beast. Things show up on eBay, and I'll keep an
eye out there. There's a local shop that has Velleman probes tho
I don't know for how much. Where do you go for probes?

Also, anybody have a preferred instructional source, "Using
O'scopes For Fun and Mayhem" perhaps?

Thanks,
--Steve.
