Is a PIM system worth the investment for a small business?

We're a small online retailer, and I'm wondering if a PIM system is overkill for our size. We only have about 200 products, but managing all the descriptions, images, and specs across our website and marketplaces is taking up a lot of time. I just can't decide if the cost of implementing and maintaining a PIM is worth it for the time savings. Is anyone else running a small business and using a PIM? Or should I just stick with well-organized spreadsheets for now?
