I used to always use the blue washout markers, but so many on this board said they used the kids' Crayola washable markers that I just had to try. I was nervous about it, but just took the plunge one day and did it. Stupid me I didn't even test them first, but I tried each color in the box, and they ALL washed out just fine. They are so much cheaper. They don't rinse out like the Mark-B-Gone pens, mind you, the quilt has to be washed with some kind of soap or detergent to get the marks out. And I would still probably use a fine-line blue washout pen if I had a really detailed fine design to draw.
