Tom,
I know some people who have had good results with the Marcotte. The hardest thing is getting a delivery date. Don't give them all the money up front. The unit is a bit heavy but solid. They claim they have a unit for a CS prop, but I have never seen one in the flesh. Try getting in touch with Ross at Simple Digital Systems. He has one on his RV-6.
