This came up several weeks ago and there was some concern about capacity on SD cards. Right now, the largest seem to have a capacity of 4 Gb., and since the BP firmware has had the card size restriction removed, this might or might not be an issue. Besides, CF cards are going to continue to be available for a long, long time just because they're used in so many different applications and they're slightly less expensive. ----- Original Message ----- From: "Michael D.
