Round Lightboxes

I found a new sources for light boxes today: DSA. Some of them are fairly affordable (less than $300), though others can run over a grand or more. There are a surprising number of items that go into making a light box with a nice even glow, particularly if it is thin. Obviously there are more high tech boxes available (edge lit boxes where the plexi is engraved with different depths of routing for even illumination for example), but these are often unnecessary for the bulk of the work we get into.
