[Elecraft] O'scope recommendations

[Jack Smith]

As Larry says, the major problem with the older scopes are that they use 
custom ICs and mechanical components that are long out of production.

The attenuators on the 465 series are a weak point and are essentially 
unrepairable and should be checked for proper operation before purchase.

I have a 465M and a Tek digital scope (TDS-430A, 2 channels, 400 MHz) 
and continue to use the 465 as it is preferable for some applications. 
(Plus, the digital scope is usually half-way across the basement, over 
by the PIC work area). For example, the 465 analog scope is better at 
displaying XY plots than the TDS430A. On the other hand, there are many 
applications that I would hate to go back to an analog scope, and it 
lets me generate graphics that can be used for illustrations.
