The discussion on repairing these has been interesting.  I have a couple 
stored away waiting for me to get around to repairing them.

The 7603 is a 100MHz scope, but the 7A18 vertical amp that often comes 
with it is only rated to 75MHz.  You could look for some 7A26 plugins 
for a little more bandwidth.

The military version is missing the character display on the screen.  
For most purposes that is a convenience, but I would think it is 
essential for using the frequency counter plugins.  Anyone know for sure?

I watch scopes on eBay occasionally.  They haven't reached collector 
status yet, so there are a lot of cheap scopes.  Opinions as to the 
value of "cheap" vary widely.

7603s are cheap.  You might also consider a 7704A if you don't mind 
bigger and heavier.  You'll get 200MHz bandwidth.

The 5440 is cheap, too, and one to consider if  the 50MHz bandwidth 
would be adequate.

The 2200 series portable scopes are a little more.  I have been 
considering one like the 2246 or 2247 but more recently thought I might 
go for something like the 2465 or 2467 and get 400MHz bandwidth.  I have 
a vague recollection that some of the scopes in this series have 
problems, so I'd like to hear any comments from people with experience.
