Hello Dave,
   I would suggest a tube scope. They're heavy, but they're also nearly bombproof. They're much more forgiving than their digital counterparts. I imagine one of these could be picked up on ebay for relatively cheap. (much much less than 500 bucks).

for example: 
http://cgi.ebay.com/Vintage-Tektronix-Oscilloscope-Model-531-Vacuum-Tube_W0QQitemZ320139147519QQihZ011QQcategoryZ104247QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
 
(or just search for ebay item # 
320139147519

Hope that helps.

Subject: Blown 150 Mhz Oscilloscope

I was dumb enough to use my oscilloscope to watch the output of a spark-gap  
Tesla Coil. I used a 1 inch piece of wire as an antenna and thought I was 
safe,  but, my 'scope is dead. It looks like channel A is completely fried, 
channel B  is completely out of whack, and the horizontal timing circuits are messed 
up as  well.
 
I feel smart, not.
 
I'm looking for advice. If you were picking up a new oscilloscope these  
days, what would you get? I hear you say, "What do you need?". I had a nice 150  
Mhz Kenwood 'scope. I've seen the USB scopes that plug into PC's but have never 
 used them. I'd love to get digital storage if I could keep it under a 
thousand  dollars.
 
Anything I should look for? Anyone have a scope in this range they're  
looking to get rid of? Advice?
 
Let me gently suggest that using a 'scope to look at a Tesla Coil is best  
done more carefully than I did.
 
Thanks,
 
   Dave Small
