I do recommend a power supply that has current limit settings. I did buy one of the switching supplies from China and while it works ok the filtering is not very good and it puts out a lot of noise in radio audio circuits.
For hobby and light duty there are several of the solder rework stations with the hot air wand and soldering pencil for less than $ 100.
If not mentioned a good stereo microscope of about 10 power . Amscope makes a good one for about $ 230. The 4000 series. It has a working distance long enough to make repairs easy.

Hi
Equally endorse the tinySA. Use mine regularly when I fix or build stuff. It's partner the nanoVNA is great for filters and antennas but I don't use it as much as the tinySA
Other useful stuff:
Good DMM
elCheapo multimeter with a dial and a needle. If you're looking for a rise or fall in some parameter nothing beats that.
Power supply where you can set a current limit. Plenty of these on the web.
If your budget will run to it get a PSU with buttons and memories. Stops that accidental spinning of the volts knob or putting 12V into a 5V circuit.
Soldering iron and rework station.
Decent function generator - plenty of choice on the web these days.
For receiver tests it's very useful to have an RF signal generator with defined outputs. I bought an Elecraft XG3 years ago. Bit pricy but worth it in those respects.
Decent scope.
My next purchase.
I've been using a Fluke99 ScopeMeter which is good at what it does up to 50MHz. In practice the scope is good up to about 15 MHz. The DMM side is great though so there will always be a place for it.
Power meter and dummy load.
Plenty of spares, components, and junk for improvisation or dealing with unobtainium.
That's my test bench.
