You can get a lot out of $10,000. A bandsaw would be my first choice, followed by hand drills if you don't have them. Vertical bandsaws are the way to go IMO, as they are very versatile.
Drill doctors or new drill bits if your bits are old.
Make sure you have the power requirements for any CNC or big machine. A manual mill can get you far too. You can push a 1HP or 1.5HP machine on a 110v outlet if the motor is built for that. However, I have a 2HP mill in my garage that trips the 15 amp breaker when I try to turn it on at 2200rpm.
Depending on your location, you can pick up a used Bridgeport manual mill for between $500-2000. Equip it with a DRO and a toolbox of tools and you get an extremely useful tool.
On tooling for any machine, you have to plan out what to get before you buy the machine. Tooling costs can easily exceed that of the machine, especially if it's used. Good calipers, 45*/30* triangles, end mills, a vise, etc. can run well above $1000.
If you find yourself in need of aluminum stock every year pick up some of that too.
