Now that I've got the router side of things covered I'd like to be able to machine things like this:

I'm looking for something that will handle upto 70mm diameter 6061 T6 or similar aluminium and about 50-100mm length. Would like to be able to thread with it too.

Budget is around £1500-2000 max. If its not already CNC I'd be converting it and that has to be factored into the price too. Not even sure if I'd get more use out of a mill instead of a lathe. But for now I can use crawl around alu with router but I can't turn parts on it so a lathe makes more sense to me.
