As far as need - I don't NEED a mill at all. Most of the peeps who do
hobby metal working don't NEED a mill, but it sure helps them enjoy
their hobby.

Well you can mill in a lathe; I tried it once; Didn't like it much.

I have 3 mills. I use my vertical mill more than my lathe for hobby
work. Can't imagine not having a vertical mill and horizontal mills
are just cool!

I have a shaper too. Now that I really don't NEED, but it is even
cooler than the horizontal mill.

He who dies with the most wins!
He who uses his tools has the most fun.
