I take a LOT of photos of cards and never like how they look. Strange angles, weird reflections, tons of glare. I don't see many cards so I don't need a pro set-up for eBay or anything, but I'd like to find a better system than "put card on table and take photo at odd angle with iPhone to avoid seeing myself in the slab plastic".

Does anyone have a good photo set-up? My criteria is simple: I need the box/cone/whatever to be relatively small and easy to set up/put away, and affordable.
