Swampwiz,
I asked about the same unit sometime back.

The good points are it takes up little space (if you already have a lap-top on your bench). It’s inexpensive and does a good job working on pinball games.
The down side is it’s not very portable (with the lap-top). It’s only 20 Mhz (which isn’t a problem on Pinball games). But like Thermionic pointed out, I just couldn’t work with the keyboard and mouse controls. For this reason I replaced it with a Hantek DSO5072P.
I think most everything on a pinball game can be handled with a DMM and logic probe but I found it to be a great learning tool. I’ve learned more about electronics with an oscilloscope than I ever knew – and I’m still learning.
