I'm new to all of this and I have some products on the way. I've read alot about PC's but i'm wondering if I should spend the money. I only plan on "macine polishing" every once in a while, not all the time. So my question is should I spend the $$ on a pc even though i'm not going to be using it all the time? Is there a cheaper "amateur polisher" that anyone recommends? I just can't see spending $100 on something that i'm not going to be using that much.
