What particular types do you still want to replace/upgrade?
For example,
Schmitz would be worth a serious look for small electrical work IMHO (designed for electronics). Best value out there I'm aware of (absolute top quality, yet half the cost or less than brands such as Erem and Lindstrom). The get rebranded a lot (i.e. CK Tools and NWS).
To give you an idea of cost, the pliers I ordered came out to ~$28 per after everything, and shipping took ~11 days.
Independent review that might be of interest (by another member).
Hemostats would also satisfy your desire for locking pliers that work great for electronics/small electrical work. Inexpensive too.
They can be modded, such as grinding out a hole in the jaw faces to prevent wire insulation damage (
example).
Couple of other items that might be of interest:
Lister Bandage Scissor (useful for removing sheathing/heat shrink around bundled wire)
Mayo Scissor (great at prepping wire <incl. stripping small gauges, just like datacom scissors>, heat shrink, mesh sheathing, ...).
Alligator Hemostat (amazing for fishing lost screws).
Knipex and NWS make some cable shears that cut like a hot knife through butter, and leave clean flush cuts (if you use them often enough to justify the extra cost). Suspect they'd be better and more comfortable than the Kobalts, especially handy if you do a lot of this.
Japanese equivalents are excellent as well, and worth checking out (better value if the prices are still cheaper than the EU brands).
When you're ready to toss those crimpers

, check out
Pressmaster. They make some of the best crimp and strip tools out there (also get rebranded a lot, by both other tool makers such as Wiha and Xcelite, as well as terminal manufacturers, such as Thomas&Betts, Molex, ...).
