I've used a few of this series (not this exact model) over the years.  They're 
OK in general, but IIRC they have a fan that gets quite noisy with age.  I've 
always found the Tek scopes more intuitive to use than HP, but these are not 
so complicated that you don't get used to it quickly enough.

Well, before I even get to that, the description would have way too many red 
flags for me to even consider this offer.  Unless you really want this 
particular scope and are prepared to repair any faults it might have, I'd keep 
looking elsewhere.
