1. Budget. $500 is a nice piece of change to work with.
This will get you a nice G540 with motors and power supply.

Look at this package.
G540 4 axis package (1PCS G540 +4 pcs KL23H2100-30-4B (3/8” Dual
shaft with a flat) 382 oz-in + 1 pcs KL-350-48 48V/7.3A 110V/230V
power supply): $549.95
2. What kind of materials are you going to cut with it? Wood
.
OK what kind of wood? Balsa is a lot easier to cut than Rockmaple.
3.What are you going to be using for a cutter head? If you are going to use a 5hp router or industrial cutting head the weight starts to become a real concern. The mass and power of the cutter, along with the type and thickness of the material to be cut, determines a lot of what is needed in the way of motors and drivers.
If you are using an dremel to do large sized but finely detailed carvings, you can get away with a lot less.
4. Based on the cutters that you will be using and the type of material you will be cutting, going slow may not be an option. Operating a cutter below its minimum speed and feed will just burn it out/up and leave a terrible finish on the part.
Conversely, if you going to be using high hp on tough material and large cutters, you may need a suprising amount of power to push the cutter into the material.
