Yokogawa is a really great scope manufacturer, in my previous department we had over $300,000 worth of yokogawa scopes/data recorders/power analyzers.
I liked them so much I bought a DL7200 and use it as my primary scope at home. I've used the DL2000(newer version of the DL1540) and it was definitely my favorite due to screen size/portability. The only problem I ran into was that the discontinued models will have zero support from Yokogawa service, and certain parts can be hard to find. There won't be any schematics, but nothing has failed in my scope since i bought it.
