I don't know of any other alternative sources for that sort of ink. The only option I can think of is to buy some big markers, pull them apart, and squeeze the ink out of the felt cores. Home depot has some really big Sharpie markers that I saw yesterday - sorry, don't recall the price. But they were the biggest darn sharpies I ever saw.
