I love my SDS2104X Plus, but the one thing I wish they'd done was make the scope wider and included separate controls for each of the four channels, rather than single controls and needing to select which channel it applies to. The SDS5000X series' controls are exactly what I really wanted, but didn't want to spend the extra money just for that. Now I see the SDS6000 Pro series also has the shared controls. I guess some people just like the smaller form factor the having shared controls allowed, but not me. To me, it seems like a step backwards. Well, I don't think I'll be in the market for a new scope for a long time, unless suddenly my bandwidth requirements jump up a lot, so in actuality it doesn't matter to me what they do with the SDS6000 Pro series. But still sometimes it's nice to dream about what could be near-perfect equipment even if you can't afford it.
10/12 bit would certainly be nice to have. Maybe after a few there will be a SDS5000X Plus model with some of the enhanced features of the SDS6000 Pro series, but at a more affordable price.
