My purchase list for my new lab -- budget $1000+, thoughts?
AnyNameWillDo:
Link to my second thread about components: https://www.eevblog.com/forum/beginners/purchasing-parts-and-basic-components-for-a-new-lab/
I'm in the US. I could use some advice for how to modify my purchase list. I'll share what I have researched so far.
My budget for my overall lab I'll say is $1000. Honestly I'm probably willing to spend more than that, but that's the number I'll work with for the moment. If I need to go over that for something special, I'm down.
Right now I am mostly looking on Amazon but if there are cheaper-but-just-as-good alternatives elsewhere, I'm all ears. One condition I want to uphold is good-quality stuff. I don't want to waste money on flimsy crap or knockoffs or specs that aren't genuine. I'd still like to buy the real deal, but simply pay the least that I can.
The reason I am making this thread is because I'm already starting to creep up on my budget and I feel like I am probably overspending, but I can't tell.
I'm a buy-once-buy-for-life type of person, so while some things may be overkill for me now, I'd rather grow into them rather than end up spending more money in the long run buying replacements and upgrades. I'd rather just buy nicer things up front that will last me a long time and cover the vast majority of possible use cases.
What should I change? What should I add?

Probably missing several other obvious things...
HB9EVI:
A variable 60Hz AC supply you'll likely not need very often; normally you work with a DC supply and variable frequency AC signal generator
as a starter project, you can build your own variable DC supply with an LM317, or if you want with current limiting with the venerable LM723, which actually still has a very good noise figure compared to the LM317

I had always heard though that this was less suitable as a beginner project since I'd have to mess around with mains? Or is that not true?
TK:
You can get a fixed 12V / 15V wall power supply to power the variable LM317 DC supply you will build, no need to mess with mains. Or you can get one of the pre-assembled ones like the DROK Numerical Control Voltage Regulator DC 5-32V to 0-30V 5A Buck Converter. They come assembled with nice LED displays.

That's awfully a lot of things for a $1000 dollars. I'm afraid you are choosing things without knowing much about most of them. (sorry, I'm being honest here) To get into electronics, all you need at beginning is a good soldering iron, and a multi-meter, perhaps along with basic tools you can buy anywhere. Everything else, you can buy and add when you have a need.
I bet you won't need a scope for quite some time. De-soldering, I won't even mess with solder wick or pump. I can make do with soldering iron and a swift hand move. Once you really need one, I'd suggest buying something good, like Hakko for $250 or so. TO ME, anything else is just problem. I went through many choices and until I found Hakko, I didn't know how EASY it was.
You really don't n need A/C power supply. Initially, you won't be needing anything but say, 5V and 12V DC. You can make, buy used, etc. If you are coming near Orlando, Florida, I'll give you one. (honest!)
50Mhz scope, you will probably regret. I'd buy nothing short of 100Mhz and if buying today, I'll probably go for more like 200Mhz, 4 channels. It's not the frequency of what you are measuring that matters. It really has to do with highest frequency COMPONNT of a given signal.
I'm not sure why wallwart is in here.... a decent power supply (above) will do just fine. After 30some years, I still don't have a helping hand. I can hold two pliers in one hand and soldering iron on the other just fine. Advantage for being an Asian, perhaps? (Chopstick reference)
I'm really afraid you are planning too far ahead. Your needs will grow but depending on direction you take, what you'll need will be different. Quality required will be different. AND.... your taste will be different. I'm more into starting with basics and go from there.
I'm sorry, I really don't mean to offend by any of what I said.
