I would go with the Heym. Great quality, and accuracy. And this is coming from a Chapuis 9.3 owner. My Chapuis shots great, but the finishing inside the boxlock was not great, and Chapuis's customer service leaves much to be desired (and this is not a French manufacterer being snooty to Americans thing, most of my French friend have said the same thing about Chapuis they just don't care about their customers). I would also like to add the smaller French firm Demas and the Rippamonti's to your list if you can find them imported here.
