With all this talk on here recently about polishers, I thought I'd have a quick look on the web to see what I could find out. The prices, where available in this country, vary hugely, so here is the cheapest. All up with a transformer about £100 which I presume excludes VAT. That's cheaper than importing one from the Sates.
