A lot of folks suggesting buying used. For many of us that are part of a school this is not an option due to purchasing rules. Make sure to check before you head down this path. Also consider your skill level with machine tools as a used tool comes with little or no support.

Please Help.
Thanks !

I didn't find the right solution from the internet.
