Jeez. The cheapest I found at a glance is €86, and the one that's of a size more like what I'd prefer is €155. For twenty-five cents less I could get a *projector*.
Now, my experience with projectors is that gosh, all the blood falls out of your arms while you're using one, but you can do things of all sizes with a projector, which you can't so much with a lightboard. (You can also use a window and some tape to trace, but that also involves the blood falling out of the arms, which is what I was trying to avoid. Plus cold arms from leaning on the window.)
So. Should I get a 10x12" lightboard (€85.50), a 12x18" lightboard (€155), or a projector (€154.75)? Discuss and advise!
