1st: "good" and "cheap" are concepts that do not quarter in comfort. Decide which you really want, and remember that the most expensive disc is the one that fails. Prodisc CDRs, I would plan on a significant failure rate. :flower:
2nd: Hub printable discs do not have any reflective layer in the hub area, so it looks different. Once printed it's harder to notice. Different brands can vary in this regard.
