I started off with a 1/2 hp double spindle motor which is what we'd used at ECA. I then laid out a humungous amount on a dustmasterbench polisher with extraction because nothing else was available, since then a lot of really great machines have come on the market which take up much less room and are much cheaper. I thought this looked a good one but still probably over your budget. Always worth waiting on Cookson discount and free delivery to bring the price down on big spend http://www.cooksongold.com/Jewellery...iABEgImvfD_BwE
