To optimize your effiecency for your dollars....buy a combo machine...
for about 500+ you can get a very decent mill/lathe/drill press combo ANYWHERE...however i would invest heavily in a digital readout for your mill and lathe operations...since these machines are not intended for heavy industry use, the handles and dials arent quite "perfect" so to make your machine the best it can be, i would seriously get a DRO...
a setup like that might run you about a grand... and use the other 1500 dollars for accessories; aka collets, endmills, center-drills, chucks, and other various gadgets.
one more resource you ought to find useful is
Harbor Freight, they specialize in overstock machines. you can get a good drill press and band saw for about 200+ bucks.
good luck
