I bought a Freud one from machine mart after my original machine mart one died,but that was after about 6-7 years of use/abuse.

My mate just bought a sealey one for £70 odd quid off eBay.I must say the freud one is really nice to use,although it's only 2 speed it just seems to bring to a shine instantly,very nice.

Make sure you get the velcro backing pad so you can make it quick release,far easier to use.
