I looked at the Chessex and weighed the costs. And went for my own.
I have 5 or 6 players at my table regularly, and I wanted everyone to have a set of 5 dice per category (attribute, gear, skill), plus a set of my own. That is 105 dice total. If i customized one of the colors with face the total is $26.25. Customizing the other two colors with two faces each is $105.00. That is a total of $131.25. Plus whatever the shipping was.
While the fabric markers I'm sure are amazing, I use sharpie markers when making notes for projects. They are permanent and will work fine -- so no cost there.
Meanwhile, after digging around on Amazon I managed to find a craft parts company that strangely had the dice I wanted in packages of 25. I picked up 50 yellow, 50 black, and 50 green for a total of $30. And shipping was free. So, $100 less than ordering them from Chessex. This means I will have all the dice I need, plus extras.
