Light box
About 30 years ago, I purchased a professional light box about 19 X 25 inches. It has a ¼ inch thick plexi top and a metal frame with two long light tubes inside, each with a switch. It cost about $225 then. Yes, it cost a bundle, but it was the best purchase I've ever made and over the years the cost is minimal. No standing at windows feeling the blood drain from my arm anymore--I just sit it on my lap or the table and trace away. Have only replaced one florescent bulb in all that time. And it's large enough to do most sizes.
