No.  The SDS2000X HD is a much higher spec'd scope than the Rigol MSO5000.  Even the SDS2000X Plus is a better scope, all considered, than the Rigol and is now almost a low cost.

They make some real nice stuff.  Generally speaking right in there with Siglent and Rigol.

Two reasons to do so:
a) Manufacturer saves money on parts that are will not be used like input jacks and precision shunt resistors
b) As there is no low-impedance input, there is no possibility for the classic cause of accidents in leaving the test leads on amps and then attempt to probe voltages...
Some manufacturers like Hioki actively promote some versions of their multimeters with non-available Amps inputs as a measurement to increase work safety in critical environments.

a) For sure.
b) Maybe, but it really limits the use of the device.  I find I need to take current readings all the time so a DMM like the Fluke 101 would just not work out for me as my only meter.  The only reason I can see having it as a 2nd meter is because of it's small size.  However, there are a lot of compact meters to be had for $50US that have a lot more going for them in terms of functionality than the little Fluke that for me woudl be better choices as a 2nd compact DMM.  The UT61 series comes to mind.

Not quite. GW Instek has been around much longer and has a much bigger revenue. They certainly have carved out a place in the professional market for a long time already. Their gear typically works as it should (or it gets fixed quickly) and they offer a much wider range of instruments.

So you'd put them in the A group?  I'll go with your estimate here as I don't have hands on experience with GW Instek.  I was just gong by what I've read or seen on YT.

BTW, I have 4 products from Siglent - none are not working as they should.  One had some tiny issues, but Like I said, Siglent got back to me in less than 2 hours to resolve the problem.  Maybe I'm just lucky, but I'm not sure that is the case.  I think you will see Siglent make serious inroads into the professional market over the next decade.
