Well, it depends somewhat on how much speed and accuracy
you are looking for. We have an Enco 3-in-1 machine at work, and it
is awful. Some of the other models with the head that can be
raised are a little better. I have a mini-mill (sold by nearly
all the dealers, now, for ~ $399 -499) for demos, and it is getting
close, but still lacks rigidity. There is a Grizzly machine with
a dovetail or box vertical column that is supposed to be pretty
good. If you don't need anything fast, then I think you could do
your 1/2" plate with that. A client of mine in the area has the
geared-head version, a little bigger, still. I would definitely
NOT recommend that model, as it has a 1500 RPM top speed.
You definitely want to be able to get 2500 RPM, 5000 would
be even better. An R-8 spindle would be nice, as so much tooling
is available for it. Otherwise, make sure it has a standard taper,
so you can get tooling from local suppliers.
