I am getting in a little late but.. for any serious new manufacturing equipment 4k is very little to work with. If you decide on a lathe try and get one with a DRO. ( we had students standing in line to use our lathe this year). It is a sharp. Fixing up the little milling machine may be good. Figure out what taper it has and get a set of collets, get a keyless chuck, some endmills 2 flute HSS is good for alu. We use our Milwaukee portable band saw all the time. Do you have a good tap and die set. A small sheet metal shear is nice. Maybe a plasma cutter (requires a good air compressor ) personally I wouldn't get a cheep CNC . In that market you get what you pay for.
