Some years ago I bought a "Mill and Drill" benchtop mill, I believe from Enco. I found it was pretty useless for all but the most basic of milling operations. Slop in the ways and undersize bearing surfaces meant you had to take tiny bites very carefully to maintain any sort of reasonable precision, and I use the word precision very loosely

.
It made for a decent drill press.
I know they're big, but if you have room a used full size Bridgeport type machine is a whole different universe. Unfortunately, a whole different price tag too.
Grizzly tools make some reasonably priced stuff.

I think Enco has a site , maybe encotools.com?
