I have been entertaining thoughts of a Blaser S-2 in 500NE but am concerned about its shootability,?rubber parts and resale. Any personal opinions on this gun?

Without having the very knowledgable members of the doubles forum having to regurgitate the same info repeatedly asked from multiple prior posters ---
What key words may I search this forum with for finding the best info on finding a cost effective double 500NE gun with the best boxlock working action for hard hunting with that that caliber?

Thank you for your patience and input.
