You can get one of these new for about $1000, but it's black and white.

That's gonna be tough for a real oscilloscope.  You can get new 60MHz 
Instek CRO scopes on e-bay for around $150 (usually about $400 msrp).  I 
just did a bunch of research on cheap digital scopes and ended up buying 
a DS1102C from Rigol:

It's kinda steep for your budget, but man it really kicks butt for the 
money if you can afford it ($1000 for 100MHz, 2 channel).  Rigol makes 
the Agilent 3000 (same as Rigol's older 5000 series).  I really like 
this scope, it does all the math plus it's color.  The sample rate is a 
bit low for 100MHz bandwidth (400Msam/sec), but the deep 1Msample buffer 
is nice.  So far, I'm really happy with it.  I haven't seen any USB 
based scope that even comes close, except maybe Clever Scope.

This is interesting too:

I don't know anything about these, but they're sure cheap enough.  The 
screen is larger than average and full VGA.

I can tell you this, I'm super impressed with Rigol's tech support.  I 
emailed them about a couple of things and they responded immediately.
