Get a decent mill is my advice.
My mill weighs between 250-300KGs AFAIK.
Having a few small problems with it atm (table shaking) but I think It was because me and my dad started fiddling with backlash and table tension.
Also try to get a mill with a square column (one where the table moves up and down rather than the head could be even better). Try really hard to get a mill that allows you to lock all axis. This stops any potenial movement in other dimensions when you dont want it (Why we originally started fiddling with backlash etc, to stop some slight movement as my mill cant lock the x and y axis

)
Decent vice is always good thing to have. I have an older vice that allows the work to be tilted and angled. And a new very nice vice that allows 360ยบ movement.
I'd also recommend getting a set of parallels, which I don't have atm and am using bits of wood
Even if you dont want CNC now, look at each mill in terms of ease of conversion, you don't want to spend lots of $$$ to not be able to do what you want in the future.
