How big the the engraving work you have planned? Would something like this work out or is it too small: [Mori Seiki NVD1500 DCG]. REMEMBER: it may not be too small now, but near every machine becomes too small at one point or another. Granted you can't see the future or know exactly how things are going to turn out, however you can make a fair assumption as to what you do or do not want to do with your equipment. The biggest cost is the machine, also the biggest cost is tooling the machine. Endmills, drill sets, reamers, carbide inserts, tool holders, indexable tooling, single point stuff (for engraving), work holding (vises, fixtures, bolting, t-nuts, etc, and an box to organize everything. This is the stuff that winds up costing thousands upon thousands. Buy quality stuff, avoid China and similar quality as you get what you pay for. You outgrow machines, rarely does someone outgrow the tooling when you enter in at the level you are inferring. Avoid Tormach and similar machines, they don't have the spindle RPM you would want and the cost is what you could get a used Mini-Mill for.
