As usual, coming in late to the discussion.
Limpet : Have you looked at Arc Euro for brushes?
First lathe was a second (at least) hand Myford ML7 Before too long needed a new Secondary belt, and then countershaft and bushes, and nut for the Cross slide. Using a Rodney milling attachment convinced me that it was not rigid enough for my use.
Warco vs Chester
Bought a RF25 (Economy) Mill/Drill from Warco. Primary belt shreddeed within six months. Motor was out of line. Replacement, with motor aligned , still going strong at least 15 years later.
Bought a small bandsaw from Warco. It cost me near £100 in blades before return. The replacement (Asked for checkover before despatch) obviously wasn't as the main casting had a crack with paint in it.
Sent it back for the larger 4.5 inch model. Out of warranty, that sent the thin steel bearing spacer through the lower bearing and seal. Replaced both bearings and seal, with a hefty brass spacer. No more problems in that area.
Wanted to buy an Imperial BH600, without stand. No quote was forthcoming, so bought a BL12-24 from the now defunct Engineers Tool Room, (VFD fitted for free when ordered). Reg Pugh even helped place it on the bench.
Tumbler gears slack and noisy: replaced immediately, and with new axles, without query. Halogen lamp ate bulbs; with improved ventilation, cannot remember last bulb failure. Only problems have been caused by my stupidity.
Design problem of placing a ball oiler behind handwheel where it was inaccessible. Relocated by self.
Spoke to Warco about possibility of obtaining ball oilers. Six arrived, FOC by post a day or two later!.
Have a secondhand Chester Super Conquest, only complaints: No means of lubricating the leadscrew bearings (Rectified by drilling and fitting ball oilers when making and fitting a graduated leadscrew handwheel.
Tailstock was off centreline. Did not look as if previous owner had moved it. No great problem in realigning it.
Those are my experiences of Far Eastern machines. Obviously with many years in Quality Engineering am not happy about the problems, but I got what I paid for. A Rolls Royce costs a lot more than Dacia, so you expect no, or fewer problems and maladjustments..
If there are problems, the after sales and service support is the vital factor, which is what my former employers tried, and still do, to provide.
An Industrial machine will be built and assembled with a view to providing reliable, durable, precise work over a long hard life, and will cost accordingly.
Hobby machines are designed and built for light duty; and the materials, life and quality will be reflected in the price.
