Are you taking classes for fun or are you thinking of buying equipment for a home shop or career change?
If you think you might be doing machining again after your class is over consider building tools that will make future projects easier. Things like V-blocks, machinist vise, angle plates , 1-2-3 blocks, sine bar...etc are very useful when your shills get more advanced.
Hell when I was in high-school shop class all we made where pot pipes and num-chucks (sp?)... if I would have known I was going to spend the next 20 years working in machine shops I would have applied my self..
