I have a HP 4951 with a tape drive. (The TD is the reason that I seldom
use it). The one problem that you frequently find in these and a lot of
other "modern" electronics is that they use internal NiCAd batteries and
the batteries go bad. I was given the one that I have because of that.
SOMETIMES it's an easy fix but in the case of my 4951 the leaking battery
had fuined the card it was on. Fortunately that card was for an option so I
was able to use the PA without it. I also got a NICE Logic Analyzer cheap
becuase of the same fault. But to make a long story short, you need to
check these out before you buy if at all posible. If it has memory problems
you should be able to use that as grounds to get it CHEAP. But you may also
find that it is ruined if the battery has leaked.

All I can say is that my experiences with this line of protocol
analyzer have been great, and if you are snooping non-exotic
connections, probably any of them will work fine. If you have some
bizarro need, you might want to google up particular models as you see
them appear on eBay (item 7506826828 has a good picture of a 4952A, as
an example.) Prices sure do seem to vary. Glad I already have a few
working ones. The non-working ones go cheap, but I have never had to
fix one, beyond the mandatory gooey capstan replacement.
