Echidna,

Buy from metalwork machinery from Hare and Forbes (Herless). They have been in the metal machine game forever. It is their true line, they just dabble in woodworking stuff. Get the Metalwork Cattledog for free from their website. They aren't a bad piece of kit, depending on what you spend. Used to work on one of their cheapest and nastiest lathes and it did the job. You will get what you pay for.
