I have a central machine 7 x 10" basically the same machine its okay, with the longer bed it will do a lot and make set ups easier. Turning mine on is a little more procedure than the bigger machines. It could stand a little more power but Im used to bigger machines. They usually come with a tool package also chuck a few cutters drill chuck live center. You will want to pick up a 6" bench grinder for sharping tools. For working brass and what your wanting to do HSS cobalt is cheaper easier to sharpen and a good choice. You dont need special wheels to sharpen it either.
These machines are light 2 guys can carry them in. I believe my 7 x 10 is 75 lbs. When I had my shop moved, both lathes the mill and surface grinder it was a all day event and 800.00. When we moved the big drill in it was a semi fork lift and skates 1600.00. Being able to carry set p and move around is a big plus. This didnt include wiring them up.
I believe youll be happy with the machine as you learn and gain experience you may want to upgrade or add a mill but this machine will do what you want. You will want to add an indicator and magnetic base.
