From my experience, getting a scanner is not worth it, especially if you’re dealing in low to mid end. I personally use a light box and my phone and post on the mobile app. It doesn’t take too long to snap pictures, and the light box makes it look good and professional. When it comes to me as a buyer on ebay, I personally prefer listings where the card has pictures in a light box. It’s much easier to see the condition of a card rather than pictures taken using a scanner. The way I think of it is I would have to make $1,000 profit on Ebay to even make the scanner make sense. If you’re dealing in low to mid end like I said, making that level of profit takes time and volume.
