In 2 weeks I can something from anywhere in the world......1 week from China.
It's not about what you can get but instead the best instrument for today's and future use....they are not expensive.
The hobbyist might pick some CRO boat anchor use in their twilight years however to advise the EE's of tomorrow to get one is just downright irresponsible.

NOT wishing to offend anyone, but while YOU may be able to get something from anywhere in the world, and YOU have the financial resources to pay some hundreds of dollars for a DSO, or professional* multimeter, or name-brand soldering station, etc... there are many people in this world who are POOR.
by POOR i mean having just a few dollars to spend on a hobby, who perhaps live in a tin shack, who access the internet via a $10 cellphone. or they may be a youngster whose parent(s) work 12 hour days and have ZERO spare cash to share once the weekly bills have been paid.
most folks on this forum likely are NOT so poor. but some are. and, indeed, most people in the world are. for those folks the "best instrument for today's and future use" is completely out of reach. so they make do with a $5 multimeter (ICL7106 based, manual ranging), a 2nd hand CRO if they are lucky, and whatever soldering device that can be scavenged for a few dollars.
cheers,
rob :-)
* by "professional multimeter", i mean a good multimeter that is CAT rated, of either workshop or tradesperson grade.

RE Cheap vintage CRT scopes:
Everything does NOT come from the internet or China!
At Paris flea mkts paid EU 5 1 ch 10 MHz Hameg, EU 25 2 ch 20 MHz Hameg. (1980s, , designed in Germany, made in France)
Similar old analog scopes on local FS websites like Craig List in USA or PAP, Le Bon Coin in France. Certainly others exist in every country!
Amateur radio fleas and estate sales are another source of great vintage equipment!
It takes time and work, and persistance...get off your mobile or PC/MAC and physically LOOK AROUND!
Seek and you will find!
Bon Chance!

No, it is not irresponsible. I will leave others to comment on whether a Siglent scope salesman is being "responsible" when they say that, or whether there is some other motivation.
--- End quote ---
he is being responsible, its just he keep suggesting Siglent brand, which is understandable, but narrowing the option a bit. there are many other options/brands like Rigol, Owon, Hantek etc, or even higher end Keysight/R&S etc, but the point is they are the same in the class more modern more usefull less risky DSO, not some boat anchor model...
i have here an old Advantest R3465 SA (still LCD version) that i got because its the cheapest in the market, thats all i can afford as hobbiest, its nearly $1K costed me. its now has some calibration issue that i dont know how to fix, not enough time resource to do finding faulty parts... then i can find much much older CRT version of HP/Tek SA, if its broken some unobtanium parts inside need replacing... who's responsible? you? the people who always like to advice on boat anchor CRT? here please pour in your professional advice if you think being responsible to poor people who want to do more thing with less. https://www.eevblog.com/forum/repair/advantest-r3465-spectrum-analyzer-repair-help-input-attenuator/msg2456370/#msg2456370

so tell me what £100 tool (i dont have to ask what £1 tool) + some imagination stretching we can use to build a 10GHz (i dont have to ask 100GHz) scope? talk rhetorical like Aristotle is easy. real engineers give concrete example! ;) cheers.

There are those with no money, or wishing to spend no money, that will take whatever they can get for free. Nothing wrong with that. However most will find to get into electronics in any serious way, you will need to spend at least little. For minimum spend and maximum gain I might propose something like Owon HDS242S as a far superior choice over any boat anchor.

You really are pitiful tggzzz, play the ball and not the man please.
If I sold any other brand, even the market leaders would you still challenge my views ?
The days for commercial use of CRO's are gone pure and simple and a POV that you may not like but my nearly 10 years in business plainly displays otherwise and the conclusion I'd already arrived at before Siglent offered me NZ distributor.
I am very fortunate to see all levels of the NZ marketplace which unless you stand in my shoes you never will with some customers taking months to scrape enough together to purchase their first decent scope after also traveling down the road I went as a hobbyist with CRO's only to discover the obvious that unreliable old boat anchors are not worth the effort if you have limited time with your projects.....whom on earth needs to have to their fix tools before being able to use them ?
But no, you see a post from me and associate to a brand rather that respect my knowledge from the hard knocks road travelled to get here ..... pitiful.
