The HP 5335A is also worth considering and is usually reasonably priced.

Yes you are right but, the question was what's the current price of
these. Years ago a few were bought for $100. Some sold as broken
were repairable. But what does a working unit cost in 2012? My
definition of "working" is that at a minimum the seller claims it
works. Which implies an offer to accept a return on a DOA unit.
On eBay I expect everything to require repair. I am happy if it works.
Being cheap I would shoot for $125-175 including shipping for a HP 5370B.
What percentage of the units on eBay do you think have passed the
operational check in the front of the manual? I expect "works" to
mean does not blow fuses or smoke. Signs of life in the photo
are a bonus...
FWIW, I repaired a 5370 that had front panel display problems.
I swapped LED digits, DIP jumpers, and driver transistors on display
board with no effect. Some digits stayed dead.
Then I separated the front display from the housing to
work on it and it started working. A close examination showed that
the screws that hold on the front panel assembly are shorter on the
bottom than the top. Someone had put a long screw on the bottom
and it shorted two traces to ground...
I am still looking for the red plastic piece that covers the digits if
someone
has a parts unit. Please contact me off-list.
I bought a 5345A on eBay for $100 that the high-res pictures in the listing
clearly showed was set for external timebase... hence no display. The
picture
also showed a two month old cal sticker. The seller had a "working" one
for
$250, and the "for repair" unit for $100.
I have the HP 5328A, 5342A, 5345A, 5370A/B each one has something it is
best
at, figure out what you really need the unit to do.
