Incidentally, somebody told me that sand red is officially retired by Lego and according to Bricklink, it hasn’t shown up in any sets since 2004. So your odds of seeing it any time soon aren’t good. Whenever I make a Bricklink order and there’s new sand red at a tolerable price (and sometimes I take a chance on used) I’ll throw it on, but it doesn’t happen often, and my entire collection of sand red still fits in a sandwich bag.
