> make sure you get the matching probes, case (if any) and user's manual;
> get a working demo of the scope to at least assure it synchs, the display

> more than $200 for it!  There are *tens of thousands* of used scopes on
> the market, they do not have a lot of resale value and are extremely
> common in government surplus auctions.  I'd stay miles away from an eBay
> or any 'net-based deal, and stick with a local seller you can meet with.
