Have had various troubles over the years and more than once I have considered just blanking the bloody things off. Anyway latest is one of my motors appears to have gone (again !) in fact it's not much different sounding with one only working. I'm sufficiently fed up with them that I can't be dealing with the aggro of getting em direct from qtp as I have in the past. If nobody out there has a new one for sale then then I'll just run the one until that packs up ..
