Other than the normal issues with blown inputs, the 5334 is a pretty rugged
beast. It's not got a whole lot of crazy stuff inside it. It does have some
custom IC's and firmware.

The simple answer is that unless you have a valid right of return, it's
never clear what you wind up with. Even a perfect seller can't anticipate
what may / may not happen after UPS bounces it to your door. 

Bid like it's broken. Don't bid on the stuff that's obviously trashed.
Always check the shipping charges and treat them as part of the cost. Accept
that you will loose a *lot* of bids. Plan on buying more than one (like 3 or
4). You may wind up with 2 out of 3 working after swapping parts and a
little TLC. Even winding up with 1 working and 2 parts donors is not that
bad an outcome. What's working fine today may have an issue two months from

The nasty part is that it may take you months to come up with a counter. It
also assumes that this is a hobby and your time isn't part of the

There's always a tradeoff....

The one possible problem is a blown front end. This will not fail the self
test. Check the sellers "completed listings" and feedback to see what esle
they have sold. If they are playing dumb on this one, but knowedgeable about
other tech stuff you may have a problem. Personally I find a faulty item
described faulty does much better on ebay than one "not known" or not shown
switched on. A asle hate the people who put "tested and working" on high
start price items that are obviously not from the photo (i.e. matched parts
missing, obvious damage) or that from the description they haven't got a
clue what it is. OK if you are starting at $10, not at $1000.

Turning on the HP5334A and just let it run through the startup self test
among other things will leave it with dashes accross the display.

Well, that's what mine do.

Having the knowledge, time, manual and will-power may be the aspects
