My choice for what you have shown:
Enco Knee Mill 100-5200, not sure if it's single phase, not sure on table size, don't know if it comes with tooling, $1,500
price is about right. I sold mine 10+ years ago for $900.
if you want to more info, search for A1-S mill (The generic model number). Usually a 1.5hp motor And R8 collet size. Made in Taiwan. Needs 120v 20A single phase circuit or change the wiring to 240V.
Good for up to a 1/2” end mill. Larger tends to chatter.
If you want a better used small mill, look for a Millrite Mill (picture below) . 2/3 scale version of a Bridgeport with three different table widths. Built like a tank and very stiff (higher stiffness = less chatter).
