Had to replace the PSU on my SB3 Classic this morning. I bought three generic units the last time this happened, so fortunately I had two spares. I checked on Ebay to see when I bought them, and it was in January of 2017, so the replacement only lasted ten months (!!!).
I'd like to buy another spare or two, and I'm wondering if anyone has found a brand/model that is more durable. Thanks in advance.

I would recommend to stop chasing for "SB3 PSUs". Things have changed and by now 5V 2.4A is commonly delivered by "fast" or "iPad" USB chargers.
Then for the USB-DC 5.5/2.5 barrel cable, I have seen some (did not mention where the positive pin was...) but perhaps the DIY option is safer/easier.
Another option is a Raspberry Pi PSU, the official one delivers 5V/2.5A sustained and comes with a fairly long cable. It is quite inexpensive I think, but YMMV. Cut the microUSB plug and replace it with a DC barrel plug and you're done.

If you have a POE switch then you could use a POE splitter

This looks interesting. So using this setup, the power is supplied to the SB3 through the ethernet cable? No fussing with splicing wires or plugs? Thanks.

It will need two more short cat5 cables if using a POE injector one if you have a POE switch.

The only thing you'll need to check is the power cable supplied with the POE splitter has a 5.5mm x 2.5mm connector for the SB3 power

I've used and trusted RS Components here in the UK both for many, many years.

Their own brand product Number 726-2836 is a professional grade 5V 4.0A supply at quite a reasonable price.
Not sure it has the right connector for the SB3 though ("2.1 x 5.5 x 9.5 mm Centre Positive")?
And a 3 year warranty.

I have this model in my spares bin but can't remember to what use I put it. (possibly Wandboard)

I always feel more comfortable when the specification has some current overhead in the hope that it will run cooler and last longer.

There must be a similar professional grade supplier in the USA

You need 5.5/2.5 center pin positive, length 11mm for an SB2 or SB3

Donít Logitech still sell them? They did so fairly recently

Many thanks to the international community. I'm going to look into this POE thing. Wish me luck.
