I know that this statement was written in bold, but I would urge you to reconsider. High quality used power supplies are fairly abundant in the USA.

I have honestly tried that route.  Either I don't feel comfortable about the device or it's in such bad shape that cosmetically it would irk me.  I know it's silly coming from a guy who would sharpie red and black on the outputs of a brand-new unit. 

Maybe I am just not good sourcing used stuff but every time I look on eBay anything decent is maybe $200 cheaper than buying it brand-new.  If I could get that unit $150 in good shape I would gladly risk it.  But I never come across those types of deals.  I also don't spend hours every day looking for a good deal to pop up so that's probably the reason why.

Other thing is what kind.
You won't need network connected smart PSU most of the time.
Most of the time simple analog one with potentiometers is good enough.
You can have several single channel ones instead of one multi channel.
You want a smart one with LAN and SCPI only if you want to write scripts to automate it.

Also some multi channel PSU have weird channel combinations. Instek GPP-4323 has 2 channels with full capacity but 15V and 5 V have only 1 A capacity. Some will argue that it would be more useful to have 3 full capability channels instead..

It all depends on your needs.

Thank you for chiming in, all of these are very valid points.  Seems like you always need more than 1 of everything when it comes to serious things.  I thought about getting several single power supplies.  I think I would easily exceed the $700 mark if I bought 3 that had similar specifications to the one I am considering or the Rigol.

Although we don’t yet have a release date, this might be of interest if you’re not in a hurry:

It looks like it might be interesting for sure.  I am not in a hurry however who knows when this might come out.  I guess if the timing is right I would love to consider it.  What is the price of this unit from the latest rumor mill?

On a different note I asked you at one point in a previous post about possibly paralleling or in series several Siglent power supplies together.  You said you would check with the company and get back on some of the technical details if it's possible.  Did you by any chance find anything out?

Oh you can be sure I’ve enquired about SPD4kX however Siglent aren’t ready to share anything about it yet.  :(

Series mode with multiple units is no problem up to the max of 500V above mains ground but offhand I can’t offer any info about Parallel mode with multiple units.
Sorry on hols for another couple weeks.
