The Rutlands catalogue says they can supply any Trend cutter at 17.5% off, just ring and quote the Trend part Number for next day delivery.
I have bought a few Trend things from them, they appear to have the parts shipped to you straight from Trend. The service was indeed next day!
I am actually going to try some Wealden 8mm cutters as they have a bigger range than Trend. Their mail order service only has a five pound small order charge so it doesn't take much to get free postage.
