I've got a 465B, its been my "main" scope for about 10 years now. This is
an excellent unit and I reccomend it to anyone. In general, most
calibration labs will still calibrate them for about $80. My only
"complaint" (and it isn't much of one) is the phenomena noted by the
original poster that the traces are somewhat "fat."

In general you can use the focus adjustment to get the spot size as small
as possible and then you will need to adjust the intensity based on the
sweep rate to get a trace that is thin enough to make adequate measurements
from. This isn't incorrect behaviour it is simply how analog scopes work.


P.S. %600 is a good price for the scope including probes, a set of 100Mhz
Tek probes (they have a special ring indicator so that the 1x/10x lamps
light correctly) are often $100 - $150
