Hello Phillip,
I have the standard model, purchased in 2001 and have had very little trouble with it.
Problems experienced are : breaking gear select levers – they are plastic and snap across the roll pin holes, I have subsequently made new Alloy ones for it, Warco keep replacements.
Second problem, which I put down to fair wear and tear was a blown motor run capacitor: cheap fix from RS.
The machine itself is strong, easy to tram and accurate on the pillar and will happily cut with a 100mm facemill on ally.
For a single phase machine, I find it very capable, with mine not only being used for model engineering but anything that will actually fit on the table.
Regards
