Hi Matt, for your requirements I think a small rigid cnc mill would best suit. If you do not intend to build your own machine I think that pre-owned will be best suited for your budget. The ex-educational machines tend to be good value for money and have usually had very little use. The DENFORD, BOXFORD, and EMCO machines may be the best candidates, but try to avoid the very lightweight (micro-mill type) machines. Most of this type of mill, whilst mechanically very sound, will probably need to be re-fitted with more modern electronics. You will often find machines that have already been up dated, but don't be too deterred if not. Modern motors, drivers and control system are improving all the time and you would get plenty o fhelp and advice on this site should you need it. Good luck. G.
