Don't throw away the baby with the bath water!
Dick's concern for the cost of some R-K displays on some helos should make him and us ask what the 429 repair/replace costs are. The economics of every type helicopter are different, and cost for repairs and replacement are driven by many factors, such as the number of helicopters, the number of displays, the specific design, the availability of the constituent parts, etc, etc.
Can I suggest (before you all pick out the drapes on the new replacement helicopters) that you ask someone who knows specifically what the 429 repair/replacement costs for its cockpit displays?
