The Merkel 96K is a blitz action and is pretty much a workhorse. The Krieghoff possibly has more options as far as barrel inserts and may have more resale value. You might also want to consider Blaser: http://www.blaser.de/D-99-Characteristics.138.0.html?&L=1 . And there always Heym, who holds the 1891 patent for a hammerless drilling.
