A while ago (October) I ordered a coil winding machine from Alliexpress.
It took a while to turn up (6 weeks or so) but it was free shipping.
Several vendors sell the same machine with slightly different labelling and features. The prices vary widely from the £450 approx that I paid for mine to over £2k for one with European branding.

It was adequately packed (survived several weeks on Chinese railway without damage) and cam with almost no instructions at all.
This wasn't a surprise and I had already located some Youtube videos and reassured myself that the machine was popular enough for there to be a good chance of getting help.
The controller is widely used (and I suspect cloned) and I was able to download a reasonable decent manual in English. It's the kind of English that seems to have been translated into Chinese and back again a few times but with the machine in front of you and a bit of patience it starts to make sense. The controller is actually quite good.
The machine came with a taping system (not shown in my pictures) and a pretty reasonable set of wire guiding parts. Fairly agricultural in design and workmanship but perfectly serviceable.
I've had the covers off the winder and it's solidly built and a reasonable design - only time will tell how reliable.
I bought a couple of wire tensioners and made my own stand for them.
The first real job I've done is winding some transformers for a low noise power supply on an RM10 pot core. There are four windings, each centre tapped and wound with Bifilar wire, either 0.28mm or 0.19mm.
One of the windings is for an isolated interface to the system so should ideally stand of 100V or more. It goes on last and has some extra insulation.
I found it very hard to get a good range of sizes of yellow transformer tape in the UK but it is available on Aliexpress in 1mm width increments and cheap.
The pictures tell the story:

I've put to tensioners on one stand.

The last winding with ptfe insulators where the wires have to share a slot in the bobbin with another winding.
I'm running the machine at 1% speed and the motor sounds a bit rough. It's much smoother at higher speeds.
So far I'm pleased with it.
