I prefer blue DMMs (ifI would care for the color :-) )
10 years ago I almost never used a magnifier, not strange because I was younger and heavy addicted to tubes. Today I do a lot of SMD and at 53 my eyes are not the best anymore and I use a Velleman magnifier
I use if for 2 years now on a daily base for my work. I removed the extra magnifier because it was always flapping around in the breeze. The spring from the second internal lens is disappeared but easy solved with a piece of wire. Most times I have both lenses down so no problem. I glued a piece of foam at the front of the headband. It works very well. The optical quality is decent enough (and I'm critical at that point)
I miss one thing in the list, invest in knowledge. It will cost you mostly time (and buy the art of electronics)
I started with an old analog 10 MHz scope and an old Fluke 77-III. I then made a powersupply with a LM317 and a LM337. A bit later I bought a second hand function generator and a griddipper (i used that a lot) There is one big advantage for having a sound electronics knowledge base, you can repair stuff and that is handy because broken test gear is cheap, often even for free.
Buy gear when you need it, you do not have to buy everything at once and you can build instruments too. Besides the PSU(s), I builded a lot more, started with easy kits and later things became more complicated and often my own design, You can build things like L meter, C meter, counter, RF generators (upto 2GHz but the first was upto 15 MHz and very simple), powermeters, 2 spectrum analysers, a poor man "network analyser" , ESR meters etc.
OK, today you can buy stuff for almost nothing in China but you learn a lot more from building your own stuff.
About the sidecutters, I started with a cheapy, then bought a 30 euro knippex. I used that for 5 years until it became to bad to use. I never really liked it. I do not like cheap tools but I will never buy an expensive side cutter again.
I took my cheapy, removed the plastic grips, it was rather soft iron so I could use some force to make the beaks parallel. Then made the jaws ultraflat and very sharp , heated the beaks redhot and then dipped it in oil. Now the steel is a lot harder and it cuts like a dream. I made new grips from a thick rubber hose.
About soldering, after a few years and several cheap irons and station(a red weller) I bought a WS81 Weller solderstation, never regretted that. Wish I bought that instead of waisting money on the cheap junk.
