It's often the other way around: Open Source can be extremely durable, since even when the original author(s) disappears or loses interest, you still have the code and can carry on if you want. "You" doesn't necessarily have to be you as a person, who may or may not have the motivation, skills, and resources to take over maintaining some project, but is the whole user community.

Regarding the Siglent, you may also want to consider this thread:

I do always measure to ground. This is something I don't understand being so new to scopes. Why would I want to measure across two points on a scope besides ground?

Think about a half-bridge driver where you want to measure the voltage on the base/gate versus the emitter/source.

Not in a simple tube guitar amp circuit. I could see that being useful in other circuits, but for me the question is specific to simple vintage tube guitar amps. Where would I benefit in a simple tube guitar amp circuit?
KungFuJosh:
To be clear, this is the type of guitar amp circuit I build, and yes, I love heat-shrink tubing. ;)

I'll leave this for those that aren't aware of it:

That looks like another (small) plus for the Siglent. It comes back to exactly what I said about the Siglent being the newer computer. So there. ;) But will there ever be an official LXI release for this? Is this 100% reliant on the github project? If that's the case then that's not a long-term, reliable solution.

The point is, the LXI/LAN speed.
With the existing SCPI command set and the inbuilt webserver that includes the command set panel you can yank info from LAN port in close to real-time, or via the USB WiFi for that matter.
