One thing I haven't seen mentioned is the general appearance of the table top. Holes and grooves can tell a lot about the machines previous life. If you haven't operated a mill with power feed and do end up with power feed you will be pleasantly surprised. No doubt you have seen them advertised at approx. $450.
Have a good day

P S The support stand on my Enco 105-1117 is wider than the mill base by approx. 3" on each side and I think that is a good feature.
